Termination of focal atrial tachycardia by adenosine triphosphate.

Abstract
An atrial aneurysm gave rise to incessant atrial tachycardia in a 21 year old Seychellian soldier. This arrhythmia was suppressed by intravenous adenosine triphosphate and ajmaline. Resection of the aneurysm abolished the arrhythmia and re-established sinus rhythm.
