What are the types of arrhythmias?

• Supraventricular arrhythmias: Arrhythmias that begin in the atria (the heart’s upper chambers). "Supra” means above. “Ventricular” refers to the lower chambers of the heart or ventricles.
• 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.
