📋Overview
This condition occurs when electrical impulses coordinating the heart's rhythm malfunction, leading to episodes of accelerated heart rate that often start and stop abruptly. These disturbances typically involve the atria or the atrioventricular node rather than the lower heart chambers.
The term encompasses several specific types of paroxysmal tachycardias that were historically classified under various names. It is defined by its point of origin in the upper portion of the cardiac electrical system, which distinguishes it from other categories of rapid heart rhythms.
