What Happens to the Heart's Electrical Activity in Supraventricular Tachycardia?
In supraventricular tachycardia, the heart rate is sped up by an abnormal electrical impulse starting in the atria.
Supraventricular tachycardia often occurs in episodes with stretches of normal rhythm in between. When tachycardia occurs, it is usually referred to as paroxysmal supraventricular tachycardia (often abbreviated PSVT). Supraventricular tachycardia also may be chronic (ongoing, long-term).
List of the Most Common Supraventricular Tachycardia Conditions

The other supraventricular tachycardias are infrequently or rarely diagnosed.
The following is a list of conditions that fit under the broad definition of SVT:
List of Supraventricular Tachycardia Heart Conditions
There are two semantic problems in the literature with supraventricular tachycardias (SVTs). From the strict but extremely broad definition, an SVT can be due to any supraventricular cause. Consequently, atrial fibrillation, atrial flutter, paroxysmal supraventricular tachycardia, and even normal exercise-induced tachycardia could fall under this designation. However, many clinicians consider SVT to be only paroxysmal supraventricular tachycardia (PSVT). The terminology may be somewhat confusing, but the large majority of SVTs are usually discussed separately in articles under their specific name (for example, atrial fibrillation). Because the principal SVTs listed above have separate articles devoted to them in eMedicineHealth, this article will be devoted only to paroxysmal supraventricular tachycardia (PSVT).
