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.

Symptoms of heart attack

A heart attack (myocardial infarction) should not be confused with stroke or heart failure. It is the condition which causes major damage to heart muscles because of sudden blockage by a blood clot. The most common symptom of heart attack happens to be chest pain. Heart failure and ventricular fibrillation are probably the most common complications in this condition. 

Clear symptoms of heart attack are:

1. Feeling vaguely ill - very vague feeling of illness is one symptom. You cannot really put your finger on what is wrong with you, but you do feel unwell.

2. Pain in left arm - pain in the arm, mainly the left arm is also one of the symptoms of an impending heart attack.

3. Sweating and heartburn - a lot of people have reported experiencing sweating, indigestion and heartburn before a heart attack. If you are sweating profusely and without any particular reasons, or having an unbearable heartburn, consult a medical specialist immediately.

4. Chest pain - feeling of fullness or tightness in the chest followed by pain is also a symptom of a heart attack. A lot of people have reported to ignore it; kindly don't.

5. Breathlessness - sudden shortness of breath and inability to do a lot of work at one point of time is not a good thing. This could be an indication of a heart attack.

6. Silent attack - the scariest of all is silent heart attack. At times, it comes with no symptoms at all. A person could be visibly physically fit, and suddenly have an attack. This usually happens with those who are suffering from diabetes mellitus.

All You Need To Know About Heart Attack Symptoms

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.

Brown Bread Vs White Bread Vs Whole Grain?

On an average a person consumes nearly 800 calories daily from added sugar.

5 Wonderful Things That Happen to Your Body When You Quit Sugar!

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.
