Yes, there are different types of SVT. Sometimes there is a single spot in either the right or left atrium (heart’s upper chambers) that can independently start this fast heart rhythm. This is referred to as “atrial tachycardia” (AT). In other cases, the fast heart rhythm is caused by an electrical short circuit within the heart’s normal conduction system. This type of SVT can be referred to as “AV node reentry tachycardia” (AVNRT). Finally, there is sometimes an extra electrical connection between the atria and ventricles (heart’s upper and lower chambers) that allows this fast heart rhythm to occur. This is referred to as “atrioventricular reentry tachycardia” (AVRT).
