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.

5 Signs of an Unhealthy Heart

The heart is a muscular organ that helps to pump blood through the circulatory system by periodic contractions and relaxations. The heart is one of the most important organs of the body so much so that a single cardiac arrest or a heart attack can lead to fatal consequences. Even so, a heart attack is one of the most leading causes of death in the country. But there are some earlier symptoms that could alert you ahead of time. The following are signs of an unhealthy heart:

1. Sexual problems

Erectile dysfunction (ED) is one of the most predictable reasons for cardiovascular conditions. Today, patients who are diagnosed with ED are also considered as cardiovascular patients. This is because the heart is supposedly not able to pump enough blood to the genital area. In case of women, reduced blood flow can hamper arousal and delay orgasms.

2. Snoring and sleep apnea

If one snores loudly enough to prevent their partner's from sleeping or resort to using earplugs, one may be at a risk of having a weak heart. Restricted breathing during sleep is connected with a host of cardiovascular diseases. Sleep apnea, a condition where breathing stops for a brief span of time, is linked with higher cardiovascular risks.

3. Swollen, sore and bleeding gums

Swollen and bleeding gums are not only symptoms of dental conditions but also of cardiovascular difficulties. Medical experts believe poor circulation of blood arises due to underlying heart conditions. Recent studies are focusing on bacteria that are believed to cause gum disease as well as plaque inside the arteries of the heart.

4. Heart Arrhythmia

Irregular heartbeat or heart arrhythmia is a common sign of a weak heart. It is characterized by both fast and slow beating of the heart. Restricted blood flow to the heart strains the electrical signals that maintain the normal beating of the heart. This is one of the common causes of coronary artery diseases.

5. Chest pain

One of the most apparent signs of coronary artery diseases is chest pain. The cause of the sharp, clutching pain in your chest can be build-up of plaque in the arteries, which could lead to fatal consequences.



5 Signs of an Unhealthy Heart

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.

Foods That Cleanse The Arteries Naturally

Be it burgers, bagels, muffins, sandwiches or simple toasts, bread has made headway into the diets of a huge portion of the populace. Although a staple diet for many since time immemorial, the consumption of bread has increased extensively in the recent past. But, which type of bread should we intake to incur the best health impacts is a question that bothers many. The general assumption is that the wholegrain variety is the best alternative. However, the barrage of marketing tactics makes it impossible to distinguish the best variety from the others. 

There are a whole lot of myths surrounding the best variety of bread and you must choose wisely before settling for one particular type. It is expedient to look beyond the overt appearance or the name of the bread, one needs to be wary of the ingredient before taking a call.

Mostly, white bread is made out of refined flour which is often striped off essential nutrients and fibers. To worsen the situation, white bread is often bleached with certain chemicals to enhance its appearance.
Certain assumptions deem brown bread as the healthier option. Unfortunately, it isn't true always. More often than not, brown bread is simply white bread with artificial coloring added to it or is caramelized. They essentially add no surplus nutritional value.

Similarly, multigrain bread can often mislead the consumers about its health impacts. Unlike whole wheat bread, multigrain breads are usually chemically treated with softened grains. This does not effectively recover the lost nutrients of the bread.

Whole wheat bread has more pronounced health benefits. It contains more wheat germ and fibers in comparison to the more processed varieties of bread. Having evaded the toxic additives, it has relatively healthier effects on our blood sugar levels.

As you realize that the bread that you eat does not necessarily affect your health favorably, wisdom lies in seeking out the least harmful variety. In that context, rye bread or spelt bread contains greater amount of minerals. Besides, bread made from barley, oats and millets have greater mineral content than the commercially hybridized varieties and promote better health.
