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.

A flu shot can prevent a heart attack! Here’s how.
Every year, heart diseases become a major reason of death all over the world. But did you know that a simple vaccine like a flu shot can be instrumental in saving you from a heart attack?
Read on to find how this simple vaccine can save your life...
Influenza or flu has been linked with heart diseases for long and patients suffering from these diseases are always advised to be cautious in the flu season to reduce the risk of heart attacks. The ‘Journal of the American Medical Association’ recently published a study, which revealed that people who have already observed symptoms of heart diseases in them, can diminish their chances of getting a heart attack and stroke by opting to get a flu shot. Among the 6735 participants of the study, 50% were given flu shots. The results observed declared that there was 36% less chance of heart diseases and stroke resulting in death in people who had received this vaccine. Moreover, recent sufferers of a heart attack were proved to be at 55% reduced threat of experiencing another major heart problem after taking the shot.
How can the flu vaccine reduce the risk of a heart attack?
The flu vaccine works towards strengthening your immune system, and thereby decreasing the risks of a potential stroke.
One theory suggests that if a person is suffering from flu, he/she experiences an increased heart rate, elevated body temperature and augmented oxygen content of the blood, besides an alteration in the consistency in blood, which can give rise to a blood clot. Now, heart attack is mostly caused when an artery of a person is 85-90 per cent blocked by plaque, but a person having flu may be at a risk of getting it merely with 40 per cent artery blockage. The function of the flu shot is to prevent flu, which in turn prevents plaque build up in your body, thereby reducing chances of a heart attack.
Another hypothesis is that the flu shot intervenes with the functioning of the immune system of your body, and helps in developing antibodies, which provide better protection against different types of infections, thus preventing heart attacks and strokes.
