What Happens When the Electrical Activity of Your Heart Changes?

The heart's electrical conduction system plays a very important role in cardiovascular functioning. Also known as the atrioventricular (AV) conduction system, it regulates and controls the timing of the heartbeat.

How does the heart's electrical conduction system work?

There is a collection of electrical cells in the upper right atrium of the heart known as the sinoatrial (SA) node which acts as a natural pacemaker and generates electrical signals. These signals travel through specialized electrical pathways and stimulate the muscular walls of the heart to contract in a rhythmic manner. This gives rise to the heartbeat that pulses at a specific frequency every minute.

What is the effect of fluctuations in electrical activity on the heart?

The standard heart rate in human being ranges from 60 to 100 beats per minute. It slows down when a person sleeps and speeds up when one experiences physical or emotional heightening. These fluctuations are triggered by the brain or other systems of the body and signal the SA node to generate charges more rapidly or slowly. This leads to spikes and drops in the heart rate, depending on the nature of the situation.

What happens when there is dysfunction in the heart's electrical activity?

When the heart's electrical conduction system does not function properly, it leads to the occurrence of a condition known as arrhythmia or abnormal heart rhythm. This happens when electrical impulses are generated in an irregular manner and causes tachycardia (rapid heartbeats) or bradycardia (slow heartbeats) which takes place in jarring infrequent tempos.

What causes fluctuations in the heart's electrical activity?

There are various kinds of triggers that cause the heart rate to fluctuate. The exact nature of fluctuation also depends on the type of trigger. A few everyday examples of these causes are as follows:
- Exercise and strenuous physical activity increases electrical activity as the heart is required to beat faster so as to increase the supply of blood and oxygen to the muscles.
- Sleep and rest reduce heart rate as the body is not needed to exert itself.
- Release of adrenaline into the bloodstream causes the heart rate to spike up.



What Happens When the Electrical Activity of Your Heart Changes?

Postural Tachycardia Syndrome or POTS, what this condition entails is a sudden and abnormal increase in the heart beat of an individual, causing them difficulty in breathing, dizziness, and even blackouts.
There are some factors that can trigger the situation and stem the sudden rise in the heart beat. Meeting with a medical expert may help bring the situation under control.

What is Postural Tachycardia Syndrome?
Postural Tachycardia Syndrome or POTS is a cardiovascular condition that is caused due to the sudden shift from an upright position to a supine position or vice versa. It is this sudden increase in heartbeat of an individual that is referred to as Tachycardia.

The longer you overlook this condition, the bigger is the trouble you are putting your health in. This is when it becomes extremely important for you to get in touch with a medical expert, who can offer you perfect consultancy, diagnose the causes and also find a result for the same.

What Causes POTS?
According to medical specialists, there are some factors that this condition stems from and it all differs from one person to the other. Some of the most common causes of the condition are-

Joint Hypermobility Syndrome
Faulty Gene
Poisoning
Amyloidosis
Lupus
Diabetes
Sarcoidosis
Siogren s Syndrome
Cancer
Signs of Postural Tachycardia Syndrome:
There are multiple signs that indicate that an individual is stricken by Postural Tachycardia Syndrome. Some of the more common signs and symptoms include:

Orthostatic Hypotension: Orthostatic Hypotension refers to the sudden increase in the heart beat by at least 30 beats per minute, within or after 10 minutes of rising up from a sitting or lying down position. Though the condition increases the heart rate, it does not trigger any drop or rise in blood pressure. Certain medications used to diminish this effect often extend some side effects, such as lightheadedness, palpitation, difficulty to breath, discomfort in the chest, weakness, heaviness in the chest area, nausea, cognitive difficulties and also stain on the vision.
Effects in Response to Postural Change: Almost one-third of the people with Postural Tachycardia Syndrome are noticed to faint as a result of the increased heartbeat, almost 40 beats minutes, instead of the chance in postural position. Other symptoms under this head include a headache, migraine, disturbance in sleep, fatigue, acrocyanosis or blood pooling in feet, etc.
Ehlers- Danlos Syndrome (EDS): Sometimes POTS is found to coexist in an individual with other conditions, such as EDS. This condition makes an individual prone to dislocation of bones, greater laxity in skin, loose- clicking joints, chronic fatigue, reduced level of tolerance towards any exercise, etc. According to medical specialists, though these are common symptoms of POTS, there might also be other signs. These signs and symptoms differ from one person to the other.
When Should You Consult a Doctor?
The moment you experience a POTS attack or for that matter notice some of the symptoms of the condition, it is time for you to consult a medical expert. The doctor will give you valued consultation, as well as diagnose the condition properly, thus finding the best treatment and suitable medication for you.

Postural Tachycardia Syndrome - All You Need To Know About It?

Cardiomyopathy is a serious heart disease. It is a disease associated with the heart muscle or myocardium. In this disease, the heart muscles get weak and fails to pump blood to the organs of the body. It has several categories. The categorization depends upon the range of factors. In this disease, irregular heartbeat is observed. These irregularities can lead to heart failure or attack or can trigger problems in the valves. It is important to take care of your heart to avoid such a condition. It is also advisable to see a doctor as soon as the symptoms are noticed to avoid greater damage.

Types of Cardiomyopathy
This disease can be divided into four categories. These are as follows:

Dilated Cardiomyopathy: It is the most common type. It occurs at a time when the heart muscle gets too weak to pump blood properly. The muscles of the heart get thinner and weak. In fact, this also leads to the expansion of the heart chambers. In common terms, it is also referred to as enlarged heart. In most cases, this is inherited or caused by some coronary artery disease.
Hypertrophic Cardiomyopathy: This is genetically transferred to the patient. In this condition, the heart walls get thicker and this hinders the smooth flow of blood. It is one of the most common types of Cardiomyopathy.
Arrhythmogenic Right Ventricular Dysplasia (ARVD): This is a very rare form. It can cause sudden death, especially in young athletes. In this disease, fat and fibrous tissues are responsible for replacing the muscles in the right ventricle. This leads to an abnormal rhythm.
Restrictive Cardiomyopathy: It occurs as the ventricles of the heart get stiff and are unable to relax. This prevents them from getting filled up with blood. Under this situation, you might have to go for a heart transplant.
Other Types: Some of the other types include Peripartum Cardiomyopathy (the one which occurs after pregnancy), Alcoholic Cardiomyopathy (happens due to excessive intake of alcohol) and Ischemic Cardiomyopathy.
Treatment of Cardiomyopathy

The treatment of Cardiomyopathy depends upon the extent of damage caused. It might not require treatment if symptoms are not very troublesome or prominent. It may be dealt with certain lifestyle changes, adjustments and medications, in cases those needs to be addressed.

Tips to deal with Cardiomyopathy
1. Maintain a healthy lifestyle by getting an adequate amount of night sleep. Go to bed early and wake up early too.
2. Don t spend long hours in watching television or work till late night
3. Eat a lot of fresh and green-leafy vegetables daily.
4. Avoid the intake of spicy, oily and fast foods.
5. Consume home-cooked food only. Avoid eating out at restaurants or street-side joints.
6. Don t drink excess coffee, tea or aerated drinks.
7. Don t consume alcohol or smoke up cigarettes.
8. Don t live a sedentary life and be a couch potato. Workout and exercise on regular basis.
9. Avoid emotional outburst and try to keep a control over your reactions.

Cardiomyopathy - Tips To Help You Deal With It!

Be it burgers, bagels, muffins, sandwiches or simple toasts, bread has made headway into the diets of a huge portion of the populace. Although a staple diet for many since time immemorial, the consumption of bread has increased extensively in the recent past. But, which type of bread should we intake to incur the best health impacts is a question that bothers many. The general assumption is that the wholegrain variety is the best alternative. However, the barrage of marketing tactics makes it impossible to distinguish the best variety from the others. 

There are a whole lot of myths surrounding the best variety of bread and you must choose wisely before settling for one particular type. It is expedient to look beyond the overt appearance or the name of the bread, one needs to be wary of the ingredient before taking a call.

Mostly, white bread is made out of refined flour which is often striped off essential nutrients and fibers. To worsen the situation, white bread is often bleached with certain chemicals to enhance its appearance.
Certain assumptions deem brown bread as the healthier option. Unfortunately, it isn't true always. More often than not, brown bread is simply white bread with artificial coloring added to it or is caramelized. They essentially add no surplus nutritional value.

Similarly, multigrain bread can often mislead the consumers about its health impacts. Unlike whole wheat bread, multigrain breads are usually chemically treated with softened grains. This does not effectively recover the lost nutrients of the bread.

Whole wheat bread has more pronounced health benefits. It contains more wheat germ and fibers in comparison to the more processed varieties of bread. Having evaded the toxic additives, it has relatively healthier effects on our blood sugar levels.

As you realize that the bread that you eat does not necessarily affect your health favorably, wisdom lies in seeking out the least harmful variety. In that context, rye bread or spelt bread contains greater amount of minerals. Besides, bread made from barley, oats and millets have greater mineral content than the commercially hybridized varieties and promote better health.

Brown Bread Vs White Bread Vs Whole Grain?

During breathing activity, chest wall moves out & in, lungs expand & relax. For the smooth movement of the lungs inside the chest cavity, they are lined by pleura.

Pleura includes two thin linings, the layer lining lungs is called visceral pleura and the one lining chest wall is called parietal pleura. The cavity formed between these two layers is called Pleural cavity. It contains a small amount of lubricant called Pleural fluid which helps smooth sliding of two pleural surfaces. Any condition which results in inflammation of the pleural surfaces or accumulation of excessive fluid in the pleural cavity gives rise to symptoms attributable to pleural involvement or disease.

Pleural effusion is nothing but the collection of excess fluid in the pleural cavity. Excess fluid in the pleural space is not normal and can occur due to a variety of reasons. Depending on the chemical composition it is broadly divided into two categories, transudate and exudate. 


What Causes Pleural Effusion?

1. Transudate pleural effusions 

Transudate pleural effusion is formed when fluid leaks from blood vessels into the pleural space. Chemically, transudates contain less protein and LDH than exudates. It is generally seen in the following conditions.

Congestive heart failure

Liver failure or cirrhosis

Kidney failure or nephrotic syndrome

Peritoneal dialysis

2. Exudate pleural effusions 

Exudate pleural effusion is caused by inflammation of the pleura itself and are often due to diseases involving the lung. Following are some common illnesses giving rise to exudate pleural effusion.

Tuberculosis
Pneumonia
Lung or breast cancer
Lymphoma
Pulmonary embolism
Post chest wall trauma or surgery
Asbestosis and mesothelioma
Secondary to intra-abdominal pathology 
Pancreatic pseudocyst, etc
Symptoms of Pleural Effusion -

Chest Pain: Chest pain is mainly due to irritation of the pleural lining. The pain is sharp, localized and worsens with a deep breath, yawning, coughing which is usually described as pleuritic. If the effusion causes inflammation of the diaphragm the pain may be referred to the shoulder or the upper abdomen. As the pleural effusion increases in size, the pain may increase or disappear altogether due to the separation of inflamed pleural surfaces.

Shortness of breath: As the effusion grows larger with more fluid, the harder it is for the lung to expand and the more difficult it is for the patient to breathe resulting in shortness of breath.

Other Symptoms: Other symptoms are generally attributable to the underlying disease process.

Diagnosis of Pleural Effusion -

Patient s Detailed History and Clinical Examination are the mainstays of diagnosing pleural effusion and it s the underlying cause. Following investigative modalities are generally opted for working out the final diagnosis before instituting appropriate therapy.

Chest X-ray: X-ray will help indicate the presence of fluid. 
Chest Ultrasound(USG): will help in confirming the presence of the fluid and it s localization which in turn can guide the physician about its quantity and its capability.
CT Scan: CT scan of the chest may at times be required to ascertain the underlying cause or to know about any other co-morbid conditions.
Thoracentesis: Thoracentesis is a procedure used to sample the fluid from the pleural effusion. Using a long thin needle, fluid can be removed and sent for testing to confirm the diagnosis.
This can be just for diagnostic purposes or can even be used as a therapeutic procedure.
Chemical analysis of the fluid will help determine the type of pleural effusion.
Treatment of Pleural Effusion -

Treatment of underlying Disease: The treatment of a pleural effusion usually requires that the underlying illness or disease is treated and controlled to prevent the accumulation of the pleural fluid. Like anti-TB therapy for Tubercular etiology or treatment of Cancer in malignant pleural effusion, etc.

Thoracentesis: As discussed earlier Thoracentesis can be used as a therapeutic procedure to remove excess fluid and help lung expand and function properly.

Tube thoracostomy: Thoracostomy or chest tube insertion may be done to drain and treat fluids which cannot be removed by needle aspirations, e.g. empyemas (pus collections).

Pleurodesis: Some pleural effusions reoccur multiple times; sclerosing agents that induce scarring such as talc or tetracycline was used to prevent a recurrence.

Decortication: If sclerosing agents fail, surgery may be required, called Decortication.

Pleural Effusion - What Is It?

Stroke is a condition known to all for its deadly impact. Even if the affected person survives, the after-effects can be immensely debilitating right from affecting movement to speech. Being informed, you can protect yourself and your loved ones from both ischemic and hemorrhagic stroke. Here are the common signs of stroke that you should be aware of:

Numbing of arms and legs: Many people wake up and find that their arms and legs are numb and they tend to assume that it is due to compression of the nerve. But the actual reality is that the flow of blood through the arteries running up to the spine is reduced, and it has led to weakness or numbness on either side of the body.
Double vision and blurriness: Vision problems can also be a strong indicator of stroke even though most people think it is due to long hours of work or aging. When you see two images of the same object, it doesn t have to mean that you are reading too much. It could mean that the blood vessel in charge of supplying oxygen to the eyes has been disrupted or blocked.
Slurred speech: Some medicines, particular painkillers can cause speech issues. But this is not the case always; if it is not a side effect that you typically experience after taking painkillers, you should consult a healthcare expert without any delay. 
Confusion and trouble over thinking and articulating: When you find yourself in a state where you cannot recall the right word to explain the right thing, you may rest assured that it is an issue stemming from the stroke. If you find yourself to struggle thinking or finding a word very commonly, then you are heading for big trouble.
Balance problems: Some people have balance issues, and they think it is due to the dose of alcohol, but experts say it is crucial to identify whether this assumption is correct. You will never have delayed balance problems, and therefore, you cannot blame a drink that you had last day. So, if you have balance issues without any identifiable reason, it is advisable to call a doctor.
A headache that becomes intolerable at times: Headaches can be a sign of a migraine but in case you are not prone to this ailment, then the debilitating headache could indicate a stroke. Migraine headaches can also mean stroke since both of them have similar signs and symptoms.
Fatigue that won t let you stay upright: If you are not doing any physically strenuous job but still feel tired most of the time, it could be a warning sign of stroke. If it continues for over a week, it is recommended that you consult an expert immediately.
Equipped with this knowledge, stay aware and pay attention to the indications your body gives to take care of yourself.
