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 Symptoms that Indicate Your Heart is in Trouble!

Your heart gives you warning signs before the onset of a major problem. You may not even know that you are at risk of one or more heart diseases if you fail to notice these small signs that your heart sends out. Even a minor symptom, like chest pain, can indicate that your heart may be in trouble. While there could be many causal factors for a heart condition, here some symptoms, which are possible indications of a heart disease and should not be ignored in any case.

1. Chest pain or discomfort

This symptom is the most common one, which indicates that your heart is not healthy. It usually comes in the form of a pain, pressure or tightness in the chest and may happen due to a blocked artery. This may be an early warning sign of a heart attack and you should seek professional advice before it turns into a major problem.

2. Excessive sweating

If you often sweat without any valid reason, it might be a sign to be concerned for. The sweating experienced will feel more like the one that arises due to stress rather than common perspiration experienced due to any vigorous physical activity.

3. Difficulty in breathing

Shortness of breath is an indication that you are at high risk of getting a heart attack. The symptom includes having difficulty in breathing and feels similar to the panting experienced after a long run.

4. Nausea and frequent stomach problems

If you experience nausea, heartburn, indigestion or abdominal pain frequently, it may be the result of an unhealthy heart. Of course, these signs may be due to other diseases as well, but if you experience any of the other symptoms of heart problems too, it's highly probable that your heart is in trouble.

5. Exhaustion

If you fall into the high-risk zone of being a potential heart patient, you may feel exhausted after doing some simple chores, which didn't tire you earlier. Common examples may be climbing the stairs or carrying something from your doorstep inside the house to name a few.



5 Symptoms That Indicate Your Heart Is in Trouble!

Cardiac or Heart Arrhythmia is a condition which results in disruption of heart s normal rhythm. Due to this, the heart may beat too quickly, too slowly or have an irregular rhythm. Though most of the arrhythmias are not harmful but at times they can have serious consequences, which might turn to be fatal. Differences in heart beats can lead to the restriction of blood, that gets pumped around the body, hence causing damage to the brain, heart and other organs of an individual.

Now we would take into account the causes behind the occurrence of this heart condition.

Causes

Interruption to the electrical impulses in any form that lets the heart to contract can result in arrhythmia. A person with a healthy heart should have a heart rate of anywhere between 60-100 beats per minute while the body is at rest.

There are a number of factors which can cause the heart to work inefficiently, which include:

Alcohol Consumption: If you are used to drinking alcohol varying from light to moderate, the chance of irregular heartbeat increases. A recent study has shown that with every drink consumed per day, the risk of atrial fibrillation increased by 8 percent. Men and women both are at equal risk for irregular heartbeat. Irregular heartbeat is caused because drinking leads to damage of the cells, which in turn leads to causing damage in small areas of fibrous tissue within the heart.

Anxiety: Arrhythmia from anxiety is when the heart feels like something happened due to which it tries to overcompensate and beat quickly. This leads to heart skipping a beat, getting squeezed or undergoing heartbeats at a rapid pace.

Excessive Cosumption of Coffee: Caffeine is a stimulant and tends to speed up heart rate, so consuming too much coffee can lead to the problem of arrhythmia.

Deficiency of Magnesium and Potassium: Magnesium and Potassium deficiencies in one s body can cause Arrhythmia. The deficiencies can be caused due to less intake of citrus fruits and vegetables like potatoes, kiwi, papaya etc.

Symptoms

Arrhythmia can produce a broad range of symptoms which affect the proper functioning of heart. Some of the most serious symptoms are:

Fatigue: If you feel that you are getting fatigued quite easily, then it s a clear symptom of arrhythmia.

Dizziness: A sense of dizziness creeps in when you are having the problem of irregular heartbeat.

Lightheadedness: Feeling light on the head is another symptom of Cardiac Arrhythmia, as there is fluctuation in the amount of blood that reaches the brain through the heart.

Treatment Options

Problem of irregular heartbeats, especially if it s on the slower side, can be solved through the placement of certain devices like pacemaker, which can speed up one s heart rate.
Faster heartbeats can be treated through blood-thinning medications, which would help keep threatening blood clots from getting formed.
Doctors can even go for Catheter ablation, wherein they would thread one or more catheters through the blood vessels of one s heart. Electrodes at the catheter tips can make use of extreme heat, cold or radiofrequency energy to damage a small sport of heart tissue and create an electrical block along the path, that s causing one s arrhythmia.

Cardiac Arrhythmia - Factors That Can Lead To It!

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.

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.
