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?

On an average a person consumes nearly 800 calories daily from added sugar. This does not just include natural sugar found in fruits or milk but the processed sweet sugar as well, that is added to cakes, tea, coffee, confectionery and even pasta sauce and salad dressing. However, it is possible that you can limit your sugar intake or even quit it to get some truly amazing benefits.

When you take this hard decision, you may experience withdrawal symptoms such as mild depression, anxiety or restlessness. But if you remain adamant and continue with your decision, your body will soon show some incredible results that you couldn't have imagined.

Here are a few of them:

1.&nbsp;Your heart will beat happily

Sugar raises insulin levels that activate the responses of sympathetic nervous system thereby elevating your bp and heart rate. When you cut down on sugar, your ldl cholesterol will decrease by 10% and triglycerides will reduce by 20-30%. And your risk of heart attack will reduce manifold.

2.&nbsp;Your weight fluctuations will be gone

With the exception of fruits, sugar is mostly present in processed or high-carb foods that contain loads of other unwanted constituents like fat etc.

So when you quit sugar, your body has to no longer worry about those unwelcome calories and your weight will stop moving right and left across the scale.

3.&nbsp;Digestion will become efficient

When you quit sugar, the digestive system becomes more efficient. Since your stomach and intestines have to no longer worry about those difficult to digest processed foods, their abilities and functioning improves. Even your colon begins to work better, may be you take more trips to the restroom, so things get even more on track.

4.&nbsp;No more acne troubles

Sugar triggers acne troubles. When you cut it down, you will no longer be troubled by those zits that dampen your looks. Your skin will actually clear up, cracks will disappear and you will get a healthier skin.

5.&nbsp;You will no longer have sweet craving

With sugar, there is a huge negative, as you enjoy sweets, you crave for more sweets. But if you quit sugar, slowly you will begin to avoid foods that contain sugar and as a result, whenever you will eat anything that has sugar, it will taste over sweet and you will not be able to have large portions. This means no more cravings for sugar!

5 Wonderful Things That Happen to Your Body When You Quit Sugar!

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!

Bradycardia is a condition which in basic terms means slow beating of the heart. In most cases, the typical rate is 60 to 100 beats in a minute when the person is at rest. In case your heart beats less than 60 times in a minute, then it is slower than normal. But a slow heart rate is not always a health concern even though sometimes it could indicate issues with of the heart.

What could bradycardia mean?
Some people with slow heart rate or bradycardia tend to be very fit, and they have no underlying health issues. Athletes and healthy young adults often have a heart rate lower than 60. But in others, bradycardia indicates that the natural pacemaker of the heart is not working well, or the electrical pathways have been disrupted. In severe forms of the problem, the heart may beat so slowly that it fails to pump adequate blood for meeting the needs of the body. This may show some symptoms and could be fatally dangerous.

What are the causes of bradycardia?
There are various causes of bradycardia, and some of them include:

Alterations in the heart which results from aging
Health conditions that slow down the electrical impulse through the heart. This may include electrolyte imbalance, low thyroid levels, and others.
Diseases which may disrupt the electrical system of the heart including heart attack, coronary artery disease, and myocarditis.
Certain medications that are used for treating heart problems like high blood pressure or hypertension, arrhythmia, and beta-blockers, and digoxin.
What are the symptoms of bradycardia?
When a person has very slow heart rate, he or she may experience lightheadedness or dizziness, feeling short of breath, having difficulties in doing normal activities or exercising, having chest pain, feeling tired and fatigued. In some cases, it is seen that the person may have palpitations, feeling confused, trouble in concentrating and fainting.

What s worse, some people don t have any symptoms at all, or their symptoms are so negligible that they think they are caused just because of aging. The best way to understand whether you have this problem is to take the pulse, and in case, it is slow or uneven, you must talk to a doctor.

How is bradycardia diagnosed and treated?
Bradycardia tends to come and go from time to time, and therefore, a standard EKG is not always able to detect it. A standard ambulatory electrocardiogram is used for detecting the condition, and sometimes, blood tests are also necessary.

The treatment of bradycardia is entirely dependent on the cause of the problem and its symptoms. It is worthy of mention here that in case the problem is not causing any symptoms, then they would not be treated under usual circumstances.

An Effective Guide To Bradycardia!

Heart attack, also known as myocardial infarction, is a severe condition where death of the heart muscle occurs because of the loss of blood supply. The blood loss usually happens because of the blockage of a coronary artery. Due to electrical instability, ventricular fibrillation is caused. Heart attacks may result in permanent brain damage or even death.

Symptoms of heart attack
There are many early symptoms and signs of heart attack, which should be recognized. Symptoms of heart attack vary from person to person. Here is a list of the primary heart attack symptoms:

Chest pain and discomfort:
Chest pain is the basic symptom of a heart attack and occurs in different forms. The chest pain has a pressure, fullness and squeezing sensation and starts from the center of the chest. The pain may go away and re-occur and may spread down to other limbs of the body.
Headache, toothache:
The chest pain occurring due to a heart attack spreads all over the body and the jaw. Even the back and head are affected. Sometimes pain in these regions is present while chest pain is absent.
Shortness of breath:
A gasping sensation or feeling shortness of breath is another common sign of a heart attack. Such breathing difficulty is called dyspnea. The shortness of breath occurs before or during the chest pain.
Nausea and vomiting:
The feeling of nausea or sickness in the stomach is another possible symptom. It is accompanied by belching or burping and sometimes, the heart attack is associated with a feeling of indigestion. Nausea is more common in women. Vomiting also occurs alongside nausea.
General epigastric discomfort:
In several cases, patients describe the pain of a heart attack as stomach pain. The pain is heavy and uncomfortable and persists for several minutes.
Sweating:
Perspiration or sweating occurs during a heart attack and the patient experiences cold sweat in avid amounts.

Emergency treatment for heart attack-
A person who has a heart attack should be rushed to a hospital.
Several tests are carried out to detect the cause of the attack. A 12 lead ekg is carried out to supervise electrical activity within the heart and detect the damaged areas.
Blood tests are undertaken to check enzymes and in certain cases, cardiac catheterization is required where pictures of the blood vessels are examined.
Emergency medicines are given to the patient to stop the formation of blood clots and include aspirin, heparin and other drugs. Other medicines are given for thrombolytic therapy, which dissolve already formed blood clots. They work to reduce the heart damage. Nitrates are also used.

A heart attack is a severe condition and must be attended to immediately. Emergency treatment procedures are essential to save the life of an affected person.

Heart Attack - Signs, Symptoms and Emergency Treatment

Symptoms of heart attack

A heart attack (myocardial infarction) should not be confused with stroke or heart failure. It is the condition which causes major damage to heart muscles because of sudden blockage by a blood clot. The most common symptom of heart attack happens to be chest pain. Heart failure and ventricular fibrillation are probably the most common complications in this condition. 

Clear symptoms of heart attack are:

1. Feeling vaguely ill - very vague feeling of illness is one symptom. You cannot really put your finger on what is wrong with you, but you do feel unwell.

2. Pain in left arm - pain in the arm, mainly the left arm is also one of the symptoms of an impending heart attack.

3. Sweating and heartburn - a lot of people have reported experiencing sweating, indigestion and heartburn before a heart attack. If you are sweating profusely and without any particular reasons, or having an unbearable heartburn, consult a medical specialist immediately.

4. Chest pain - feeling of fullness or tightness in the chest followed by pain is also a symptom of a heart attack. A lot of people have reported to ignore it; kindly don't.

5. Breathlessness - sudden shortness of breath and inability to do a lot of work at one point of time is not a good thing. This could be an indication of a heart attack.

6. Silent attack - the scariest of all is silent heart attack. At times, it comes with no symptoms at all. A person could be visibly physically fit, and suddenly have an attack. This usually happens with those who are suffering from diabetes mellitus.
