Is Your Heart Beating Abnormally? Find Out Here!


The heart has a rhythmic capability to beat and pump blood to our body and remarkably, does so without fail, throughout our life. The rhythm has been destined to beat in certain prefixed numerical limits and with certain regularity. Arrhythmias are disorders characterized by abnormal beating of the heart. Arrhythmias can occur in a healthy heart and be of minimal consequence. At the same time, they may co-exist with diseased heart and may be life-threatening or may cause, stroke, heart failure, or sudden death.

An arrhythmia occurs when the normal electrical cycle of the heart is disturbed. Normally, tiny currents activate the upper part of the heart, just before the bottom part of the heart, which are the muscular chambers that pump blood around the body. Fast arrhythmias are referred to as tachyarrhythmias. When the heart goes too slowly due to a failure of electrical activation, it is referred to as a bradyarrhythmia. Most arrhythmias arising from the top of the heart are troublesome but not life-threatening. Many arrhythmias arising from the lowest of the heart, are life-threatening.

Causes of Cardiac Arrhythmias

Some cardiac arrhythmias result from congenital heart defects that run in families. Others arise from a variety of diseases that develop in individuals over a period of years. Others still result from sudden events such as heart attacks. They may also be the result of excessive alcohol, smoking, or certain drugs. Rarely despite extensive investigations, no cause is found of their occurrence. Cardiac arrhythmias may be symptomatic or may cause a variety of warning symptoms such as palpitations or rapid thumping in the chest, feeling tired or light-headed, getting unconscious, having shortness of breath, or chest pain.

Types of Arrhythmias

Following are the different types of cardiac arrhythmias:

1. Atrial fibrillation: The heart beats too fast and irregularly. This type of arrhythmia requires treatment and can increase the risk of stroke.

2. Paroxysmal atrial tachycardia: The heart has episodes when it beats fast, but regularly. This type of arrhythmia may be unpleasant but is usually not dangerous.

3. Ectopic beats: The heart has an extra beat. Treatment is usually not needed unless you have several extra beats in a row and/or other problems with your heart – such as heart disease or congenital heart failure.

4. Ventricular tachycardia: The heart beats too fast and may not pump enough blood. These types of arrhythmias are very dangerous and need immediate treatment.

The Remedy

Treatment depends on the type of cardiac arrhythmia you have. Some mild arrhythmias require no treatment. Other arrhythmias can be treated with medicines. In more serious cases, other treatments are available:

1. Drugs.

3. Implantable cardiac defibrillation: Can be used to stop an abnormal rhythm and restore a normal one.
