Supraventricular Tachyarrhythmias
The most common supraventricular tachycardia is sinus tachycardia which is a normal repsonse to exercise and exertion.. Abnormal supraventricular
tachyarrhythmias are defined as tachycardias that have their reentry circuit or
triggering focus located
above the ventricles. In general
there are five types of supraventricular tachycardia:
- AV nodal reentrant tachycardia
- WPW syndrome and AV reciprocating tachycardia
- Atrial flutter and atrial tachycardia
- Atrial
fibrillation
From the
standpoint of "ease of cure" using radiofrequency
catheter ablation, AV nodal reentrant tachycardia is easiest
to cure while atrial fibrilaltion is most dicfiicult to eliminate.
