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?

The news of Sridevi's sudden and unexpected demise was a shock for the entire nation and left a number of questions in the minds of the people. However, there are multiple reasons which are under speculation and can be attributed to her death - cardiac arrest, heart attack and death due to accidental drowning. Usually, cardiac arrest and heart attack are two things which most people use interchangeably, however, there is a big difference between the two. 

Difference between cardiac arrest and heart attack: 
A cardiac arrest is far deadlier considering that it comes without a warning or any prior indication of a problem. Here, the heart just stops beating and immediate first-aid can make a lot of difference between life and death. Electrical shock is the best way to revive a patient and should be given within a few minutes of such an arrest. 

On the other hand, a person suffers a heart attack when there is a blockage in the artery which prevents the smooth flow of oxygen-rich blood from reaching the heart. It is important to note that unlike a cardiac arrest the signs of heart attack start slow and persists for long. 

A heart attack is one of the common causes of cardiac arrest, but not always it is the case. A cardiac arrest happens most commonly when the heart is receiving more than 300 impulses per minute or due to absent electrical impulses. In the first instance an electrical shock is a lifesaving technique and in the second, the patient can be treated with certain medications and a temporary pacemaker. 

Symptoms of cardiac arrest:
The symptoms of cardiac arrest are immediate and extreme.

A fainting spell or a sudden collapse
Loss of consciousness
No pulse or breathing 
Symptoms of a heart attack 

Discomfort along with chest pain 
Shortness of breath
Nausea with vomiting
Sweating
Headache and jawpain
Prevention of a cardiac arrest:
What makes this a deadly condition is that you cannot tell your risks of having one and therefore the next best thing to do is to lower your risks. 
The best way to do that is to:

Follow a diet that is balanced and nutritious
Alcohol should be consumed in moderation 
Quit smoking
Stay physically active
How can you prevent a heart attack?

Keep yourself fit and exercise regularly
Keep your cholesterol level under check 
Limit your alcohol intake 
If you are obese, control your weight
Intake a heart-friendly diet.
Now that the distinction is clear between the two, it is recommended that everyone should get themselves screened for potential heart problems on a regular basis. In case of a query or concern consult an expert and get your answers. 

Cardiac Arrest And Heart Attack - Understanding The Difference Between The Two!

Performing physical activities on a daily basis always have its benefits, but doing exercise in a well-planned manner is essential for those people who suffer from either type-1 or type-2 diabetes. Becoming more active helps lower blood sugar levels and keep diabetes under control.

Relation between exercise and sugar levels
The food we consume contains sugars which are stored in our blood in the form of glucose. This glucose is absorbed by the muscles in our body, but body fat is the enemy of this absorption process. An obese person is prone to type-2 diabetes since excessive amounts of fat are present in the body which does not allow the muscles to absorb the glucose from the blood. This results in more glucose or sugar level in the blood which leads to diabetes.

By regularly exercising, a person not only burns his/her excessive body fat, but also makes use of the muscles in his body thus allowing the muscles to absorb the glucose present in the blood readily. This helps reduce the sugar level in the blood. Moreover, doing exercise on a regular basis helps increase insulin sensitivity. It helps cells to use available insulin in taking up glucose during and after physical activity.

Understanding blood glucose reaction
The duration for which you perform physical activities will determine your blood glucose level. Physical activity has its effect on your blood glucose level and can keep it in check for up to 24 hours by increasing your body s insulin sensitivity. Every individual needs to monitor how his body responds to physical exercise by regularly monitoring the blood sugar level before and after exercise or as advised by the doctor.
Once you are familiar with the results you achieve with respect to duration and types of exercises you perform you shall be able to control your blood sugar levels more effectively and prevent your sugar levels from going either too high or too low.

Hypoglycemia and physical activity
People who have diabetes should be prepared to treat hypoglycemia or low blood sugar level. Hypoglycemia is more common in people with type-1 diabetes, and people with type-2 diabetes are at lesser risk unless they are on insulin. Individuals who experience Hypoglycemia during or after exercise should consult a doctor immediately.

If you choose to resume your exercise routine, make sure you take a break and treat your low blood sugar level. Once your sugar level gets normal, you can begin your physical activity. What you need to know is that a drop, in sugar level, can occur just after exercise or even long after exercise.

Chances of a drop, in sugar level, occur in those diabetic people who either take insulin, skip meals, or exercise for too long or too hard. If you are finding it hard to keep your sugar level in check, consult a doctor immediately and follow his advice diligently.

In order to avoid hypoglycaemia, you can eat a fruit or nuts before exercise. It is also very important to hydrate yourself during the exercise. Ideally, take a fruit half hour before exercising. Keep yourself hydrated during the workout. Avoid energy drinks.

Why Exercising Is Important In Reducing Sugar Level In Blood?

Blood pressure is the measure of the resistance to the natural flow of blood in the blood vessels. The major, minor and few smaller blood vessels themselves have a thin muscular lining that keeps the vessel supple and aids the flow of nutritious blood within its tube-like structure. The vessel walls resist the free flow causing a reverse pressure that is referred to as Blood Pressure. This pressure strains the heart muscles (Left Ventricle more) to contract strongly to push the nutritious blood into the body circulation system.

Due to numerous factors, there is an increase of resistance within the blood vessels that leads to an increase in blood pressure. At a later stage, this results in lack of adequate blood flow to the end tissues and an accumulation of fluids in the various tissues/organs and a mismanagement of the nutrition-detoxification rhythmic cycle of the body. This takes a long time to develop and unless the last stage hampers body functions, it is not detected. Hence, blood pressure is known as a silent disease.

Systolic and diastolic are the two rhythms corresponding to the expansion and contraction of the heart chambers during pumping of blood into the body. This rhythm creates two distinct pressures within the blood vessels. Systolic is when the heart ventricular chamber contract to pump blood into the body, so the pressure is higher. This indicated the force or strain on the heart to push blood into the circulatory system. Hence, this count is considered significant in evaluating health parameters.

High BP as a disease is declared when three or more readings taken at different times of a day or on consecutive days shows increase in BP. Higher the BP, more strain is exerted by the heart. Since the heart is essentially a muscular organ, the muscles of the heart get affected. Sometimes, the heart muscles increase in mass and size making the heart chambers smaller in volume. This further deteriorates the circulation capability leading to numerous diseases. The strain of pumping nutrition to different body organs is also felt by the heart itself. Lack of nutrition can lead to death of cardiac tissue leading to heart failure. High blood pressure makes the heart walls thicken and becomes stiffer which makes it even more difficult to pump blood. Thickening of the heart muscles is also known as left ventricular hypertrophy and cause heart failure.

A systolic blood pressure reading that is higher than 140 mm Hg or a diastolic blood pressure higher than 90 mm Hg characterizes by high blood pressure. High blood pressure is said to be responsible for 50% of the recorded cases of ischemic strokes and also increases the risk of hemorrhagic strokes.

When heart cannot pump with enough force, there is a mismanagement in the intra-cellular and tissue fluid restoration. This puts a great strain on the kidney function. In due course of time, numerous organs of the body suffer and depending on the body constitution, immunity for rejuvenation and restoration of order, the person suffer from numerous diseases.

Diabetes worsens the situation of BP and adds to the deterioration of heart health, blood vessel health. Poor heart functioning leads to different symptoms like:

Shortness of breath
Swollen ankles or feet
Difficulty lying flat on your back
Bloating and nausea
Irregular pulse
Frequent urge to urinate at night
Fatigue
Due to disturbances in BP and other factors leading to lacking of nutrition to the heart tissue. Heart Disease complications are commonly seen with symptoms as follows:

Radiating or dull pain, especially in the chest, radiating in the arms, especially left arm, neck, back and in the stomach especially in women.

Shortness of breath; change in breathing patterns and heaviness in chest
Dizziness and fainting sometimes
Irregular pulse and palpitations
Sudden onset of excessive sweating
Unexplained fatigue, weakness and depression
Heart Disease can be treated with natural ayurvedic medicaments successfully in more than 80% of patients. Numerous ayurvedic medicines have been clinically evaluated to show positive changes supported with clinical investigation. Since ayurvedic medicines are targeted to reaching the root cause of the disturbances and to reduce the burden of the disease they go beyond the relief of symptoms.

Natural Ayurvedic medicines also participate in the rejuvenation of the heart muscles, the blood vessels, the detoxification of the body and re-balancing of health parameters, Ayurvedic treatment options are gaining great relevance and patient opt for such treatment in greater numbers from all over the world. These treatments are non-invasive and very cost effective. They are good to be taken from prevention to after angioplasty, stent or bye-pass to treat the cause of disease.

Ayurveda is a health science that takes into consideration lifestyle modifications, adequate detoxification, re-balancing body element and strengthening the system from all aspects. Ayurvedic medicines have proved useful in the treatment of Blood Pressure, Diabetes, Vascular disease (leading to atherosclerosis, blockages, wear-tear of blood vessels) and Heart disease. Today, these treatment options are gaining importance and acceptance in our society.

Link Between Heart Diseases and High Blood Pressure

As much as we take a dip in the bucket of blues and sing happy- sad songs to float and fall for the theorem of love; we are but orderlies to the emotion. We all wish if love had only been a four letter word. It, unfortunately, has multiple folds and crevices than the human mind can ever possibly think of. Nonetheless, staying in love is essential. Loving is as significant as is living; the reason being, it keeps you happy until you falter and with every faltering foothold, you emerge out as a stronger being.

A strange fact about the emotion is its tryst with wholeness. Love doesn t necessarily need an object or receptor under its radar. It could be experienced as a self - sufficient feeling. You may be full of love for a family, for a dear friend, for your lover or you could also be in love with your passion or yourself. Irrespective of perpetual disillusionment, one must try and remain in love.

Let's take a curious peek into these few ways to stay in love:

Put in efforts to look good: In any case,  beauty indeed lies in the eyes of the beholder , but finding yourself pretty is extremely important. One must take care to look good in his or her own eyes. Looking good is directly proportional to the way you feel and hence spending time on yourself helps you to think positively. You see yourself in a better light and are thus, in a position to love better.
Exercise to challenge your daily threshold: Exercising has multi - faceted effects on your overall health. If you exercise on daily basis, you witness your progress with every passing day. This encourages you to improve your flexibility and fitness. Exercising can lead to the release of the happy hormone - serotonin in one s body. Direct exposure to sunlight and consumption of food items rich in carbohydrates can also increase the level of serotonin. Exercising boosts up your confidence and makes you fall in love with your body.
Indulge in sweet things: As you grow up, you stop doing those little things that once gave you immense pleasure. Making a greetings card, baking a cake, making paper boats, going out on walks, teaching young children or doing whatever your heart feels like can actually make you stay in love.
Pursue your passion: A passion gets the best out of you; it rather steps up the limits of your talents. Pursuing one s passion makes one love oneself even more. It keeps you engrossed in your plus points, giving you little scope to brood over depressing factors.
Try having a pet to care for: Feeling responsible for your pet is a great way to discover another side of your personality. A pet gives you the warmth you had been looking for. The bond of love with a pet has had unmatched effects on a person s health.
