| ===Prevention and Cure===
| |
|
| |
| Once the acute episode has been terminated, ongoing treatment may be indicated to prevent a recurrence of the arrhythmia. Patients who have a single isolated episode, or infrequent and minimally symptomatic episodes usually do not warrant any treatment except observation.
| |
|
| |
| Patients who have more frequent or disabling symptoms from their episodes generally warrant some form of preventative therapy. A variety of drugs including simple AV nodal blocking agents like beta-blockers and [[verapamil]], as well as anti-arrhythmics may be used, usually with good effect, although the risks of these therapies need to be weighed against the potential benefits.

|
| |
| For supraventricular tachycardia caused by a re-entrant pathway, another form of treatment is [[radiofrequency ablation]]. This is a low risk procedure that uses a catheter inside the heart to deliver radiofrequency energy to locate and destroy the abnormal electrical pathways. Ablation has been shown to be highly effective: up to 99% effective in eliminating AVNRT, and similar results in typical [[Atrial flutter]].

| '''Paroxysmal atrial tachycardia''' is a period of very rapid and regular heart beats that begins and ends abruptly. The heart rate is usually between 160 and 200 beats per minute. This condition is also known as [[paroxysmal supraventricular tachycardia]].
