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.

Beet Root: Chukandar - How and Why You Should Eat It?

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!

With recent lifestyle changes, more and more people, younger in age, are falling prey to heart attacks. While some silently suffer the attack during their sleep and never wake up, others have symptoms which they dismiss as acidity or muscular pain and ignore them. There are multiple media programs that are trying to create awareness about how to identify a heart attack. If done at the right time, there is a good chance that the person can be saved.

What is a Heart Attack?

The blood vessels gradually narrow, reducing the blood flow to the target organs. This reduces the efficiency of the target organ, and if this happens to be the heart, it is known as a heart attack. The area that should ideally receive blood does not, leading to its  death.  If the damage is not severe, it can be reversed. However, if this attack happens in one of the critical areas of the heart, it can even be fatal.

Symptoms To Watch For: Very few attacks happen suddenly. Most start slowly and progress, and if identified on time, a life can be saved. The episode takes about an hour, and if you are well-versed with the symptoms, it could help identify the condition correctly and save a life. Most people use antacids and muscle relaxants to ease the situation, which does provide immediate relief, but not a proper cure.

There is a central pain which is constant, nagging, and has a squeezing like sensation. This causes discomfort and most often, this pain is in the center of the chest area, which lasts for just a few minutes. Sometimes the pain can go and come back. This pain radiates down into the arm, up into the neck area, and also into the jaw and is almost always indicative of a heart attack.

With chest pain, there is always shortness of breath which the person will experience. This is due to reduced oxygen levels in the body.

Associated symptoms include fatigue, exhaustion, nausea, dizziness, light-headedness.

There is almost always profused sweating where the person breaks into a cold sweat.

If the attack happens during sleep, the person may be snoring and may feel, as if something is choking his airway.

Due to reduced return of blood from the peripheral organs, there could be swelling of the feet and ankles.

If there is irregular heart beat (palpitations) very often, talk to your doctor about it.

When you suspect a person of having a heart attack, check for these signs. Very often, a heart attack is detectable and can be managed with timely intervention.
