Arrhythmia (irregular heartbeat): It is a condition in which your heart beats irregularly, too fast, or too slow. Symptoms of irregular heartbeat include chest pain, shortness of breath, and fast or slow heartbeat. 60 to 100 beats per minute is generally considered a normal heart rate.

Ventricular arrhythmia: It is a type of arrhythmia which begins in the ventricles (lower chambers of the heart). It causes irregular heartbeat and prevents circulation of oxygen-rich blood to the brain and body, and may result in cardiac arrest. This condition may be life-threatening and requires immediate medical attention.
