Atrial or Supraventricular Tachycardia (SVT) Atrial or Supraventricular tachycardia (SVT) is a fast heart rate that starts in the upper chambers of the heart. Some forms are called paroxysmal atrial tachycardia (PAT) or paroxysmal supraventricular tachycardia (PSVT). How it happens.
Tachycardia means a fast heart rate. Supraventricular means coming from above the ventricle. During an episode of supraventricular tachycardia (SVT), the heartbeat is not controlled by the SA node (the normal timer of the heart). Another part of the heart overrides this timer with faster impulses.
