Arrhythmia is a disorder which is characterized by improper and irregular heartbeats; be it too slow or too fast. This problem occurs when the electrical impulses that are used to regulate your heartbeat don t work in the correct manner. Your heart may beat irregularly, too slow or too fast.

Symptoms
Although this disorder does not yield many symptoms, a few noticeable symptoms of arrhythmia are slow heartbeat, or a racing heartbeat, chest pain, breathing difficulties and dizziness. Arrhythmia can lead to inefficient pumping by the heart, leading to bouts of fainting. A severe symptom of this disorder is ventricular fibrillation, wherein the ventricles tend to quiver instead of transporting blood. This symptom can cut off blood supply to the vital organs, which may lead to death.

Causes

Coronary artery disease: In this disease, arteries of the heart can get blocked, leading to irregular heart beat and impaired heart functioning.
A heart attack: An ongoing heart attack usually leads to irregular heartbeats.
High blood pressure: High blood pressure problems make you more vulnerable to this condition.
Impaired functioning of the thyroid glands: An overactive or underactive thyroid gland can lead to heart arrhythmia.
Excessive smoking and alcohol consumption: These habits can cause problems with the blood vessels in the body, thus increasing risks of this particular condition as well as other cardio-vascular diseases.
Stress: Too much stress can lead to high blood pressure; that is again linked to heart arrhythmia.
Treatment
Mild symptoms of arrhythmia do not require treatment. However, complications resulting from it warrant treatment. The various treatment options for this condition are:

Pacemaker: A pacemaker is a device that is used to regulate your heart rhythms. It is placed in the body by a surgical procedure and an insulated wire is put, connecting the heart to the pacemaker. In case of an irregular heartbeat, the pacemaker sends out impulses to correct the improper heartbeat.
Implantable cardioverter-defibrillator: This device is used to prevent a dangerous symptom of heart arrhythmia, a symptom wherein the ventricle quivers. It is similar to a pacemaker as it is also placed near the collarbone. In case it detects an abnormal rhythm, it sends out shocks to reset the heart rhythm.
Maze procedure: This is a surgical procedure wherein incisions are made on the upper heart tissue to create a scar tissue. Scar tissues act as insulators to prevent stray impulses.
Alternative therapies: Alternative procedures such as yoga and meditation can help remedy the disorder.

Is Your Heart Missing a Beat Regularly - Could it be Arrhythmia?

A heart attack does not always have obvious symptoms, such as pain in your chest, shortness of breath and cold sweats. In fact, a heart attack can actually happen without a person knowing it. This condition is known as a  silent heart attack , medically known as  silent ischemia , occurring due to the shortage of oxygen supply to the heart muscle. The causes of a silent heart attack are similar to that of a heart attack. 

They include- 

Conditions like: 
Obesity or excess weight 
Diabetes 
High Blood pressure 
High cholesterol 
Heart Diseases 
Lack of exercise 
Age, usually above 65 
Consumption of tobacco or smoking 
High consumption of alcohol 
A silent cardiac arrest makes one more vulnerable to another heart attack that could be fatal. Diagnosis: The only method to diagnose if you had a silent heart attack is through imaging tests, such as echocardiogram, electrocardiogram, Holter Monitoring or others. These tests can show certain changes which might be indicative of a heart attack. An analysis of one s overall health and the symptoms can aid in deciding whether few more tests are required. 

How would you prevent a silent heart attack? 
1.   Get your cholesterol and blood pressure count tested regularly. 
2.   Refrain from smoking. 
3.   Get your VO2 max checked regularly. 
4.   Live a healthy lifestyle: Refrain from smoking and excessive alcohol consumption; exercise daily, eat healthy. 
5.   Control high blood pressure, cholesterol, and diabetes 
6.   Be aware of your body and call on a doctor if you feel there s anything which is bothering you. 

If you wish to discuss about any specific problem, you can consult a doctor and ask a free question.

Know Everything About Silent Heart Attacks

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.

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.



What Happens When the Electrical Activity of Your Heart Changes?

Heart attack, also known as myocardial infarction, is a severe condition where death of the heart muscle occurs because of the loss of blood supply. The blood loss usually happens because of the blockage of a coronary artery. Due to electrical instability, ventricular fibrillation is caused. Heart attacks may result in permanent brain damage or even death.

Symptoms of heart attack
There are many early symptoms and signs of heart attack, which should be recognized. Symptoms of heart attack vary from person to person. Here is a list of the primary heart attack symptoms:

Chest pain and discomfort:
Chest pain is the basic symptom of a heart attack and occurs in different forms. The chest pain has a pressure, fullness and squeezing sensation and starts from the center of the chest. The pain may go away and re-occur and may spread down to other limbs of the body.
Headache, toothache:
The chest pain occurring due to a heart attack spreads all over the body and the jaw. Even the back and head are affected. Sometimes pain in these regions is present while chest pain is absent.
Shortness of breath:
A gasping sensation or feeling shortness of breath is another common sign of a heart attack. Such breathing difficulty is called dyspnea. The shortness of breath occurs before or during the chest pain.
Nausea and vomiting:
The feeling of nausea or sickness in the stomach is another possible symptom. It is accompanied by belching or burping and sometimes, the heart attack is associated with a feeling of indigestion. Nausea is more common in women. Vomiting also occurs alongside nausea.
General epigastric discomfort:
In several cases, patients describe the pain of a heart attack as stomach pain. The pain is heavy and uncomfortable and persists for several minutes.
Sweating:
Perspiration or sweating occurs during a heart attack and the patient experiences cold sweat in avid amounts.

Emergency treatment for heart attack-
A person who has a heart attack should be rushed to a hospital.
Several tests are carried out to detect the cause of the attack. A 12 lead ekg is carried out to supervise electrical activity within the heart and detect the damaged areas.
Blood tests are undertaken to check enzymes and in certain cases, cardiac catheterization is required where pictures of the blood vessels are examined.
Emergency medicines are given to the patient to stop the formation of blood clots and include aspirin, heparin and other drugs. Other medicines are given for thrombolytic therapy, which dissolve already formed blood clots. They work to reduce the heart damage. Nitrates are also used.

A heart attack is a severe condition and must be attended to immediately. Emergency treatment procedures are essential to save the life of an affected person.
