Atabrine in ventricular tachycardia.

The therapeutic efficacy of Atabrine in ventricular tachycardia has not yet been clearly demonstrated. In this case report, Atabrine stopped ventricular tachycardia and restored normal sinus rhythm following the fifth two-hourly oral dose of 0.30 Gm. Nausea and vomiting were the only toxic effects noted. Ventricular tachycardia, in this case, occurred as a complication of acute myocardial infarction. The latter's characteristic electrocardiographic picture became obvious as the arrhythmia was corrected.
