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.

6 Things that make you prone to heart diseases the most

Every year almost 2 lakh people opt for heart surgeries in India; and as of 2015 there were about 30 million people in the country suffered from heart diseases. There are several factors that increase the threat of heart diseases, among which some can be controlled and some can't. On one hand, where factors like being a man, old age, being a woman in the post-menopausal phase of life, and a family history of heart diseases are beyond your control; other risks can be minimized by making some lifestyle changes. 

Although natural processes like ageing, which narrow down your arteries and weaken the heart muscles increase the risk of heart diseases here are 7 factors, which dramatically increase your chances of getting heart diseases, while you are still young.

1. Genetic Factors: 
If someone in your family is already suffering or has suffered from a heart disease, especially at a young age, it increases your probability of getting a cardiovascular disease.

2. High Levels of Cholesterol in the Blood:
Chances of formation of plaque on the inner walls of the arteries increase with increasing levels of bad (LDL) cholesterol in the blood. This may be a major cause of the heart disease, atherosclerosis, which happens due to accumulation of fatty substances inside the arteries. 

3. Smoking:
Smoking causes constriction of your blood vessels and may damage their inner lining due to the effect of nicotine on them. This can put you at high risk of developing atherosclerosis. Moreover, studies suggest that people who smoke are twice as prone to heart attacks in comparison to non-smokers.

4. Hypertension:
If your blood pressure level is usually above normal, it can give rise to thickened arteries, which, in turn, can reduce the passage for the flow of blood through the vessels. This damages your heart health to a large extent and makes you prone to heart diseases.

5. Diabetes:
Uncontrolled diabetes increases your chances of getting a heart attack, especially because diabetes almost goes hand in hand with diabetes and obesity, which are risk factors of heart diseases.

6. Stress:
If you fail to keep your levels of stress and anger in check, they may have a damaging effect on your arteries. This can make way for strokes and heart attacks in the future.
