             What are the types of arrhythmias?

Tachycardia: A fast heart rhythm with a rate of more than 100 beats per minute. Bradycardia: A slow heart rhythm with a rate below 60 beats per minute. Supraventricular arrhythmias: Arrhythmias that begin in the atria (the heart’s upper chambers). Ventricular arrhythmias: Arrhythmias that begin in the ventricles (the heart’s lower chambers. Bradyarrhythmias: Slow heart rhythms that may be caused by disease in the heart’s conduction system, such as the   sinoatrial (SA) node, atrioventricular (AV) node or HIS-Purkinje network .
Management of Arrhythmias (Abnormal Heart Beats)

Arrhythmias can be caused by:

Abnormal extra electrical circuits in the heart Increased electrical activity of a single focus of heart muscle Scar tissue in the heart from a prior heart attack Abnormal electrical firing of the pulmonary veins High blood pressure Changes in the heart muscle (cardiomyopathy) Valve disorders Electrolyte imbalances in the blood, such as sodium or potassium Injury from a prior heart attack with scar formation
