Abstract
Bidirectional ventricular tachycardia is a rare form of ventricular arrhythmia, characterized by changing QRS axis of 180 degrees. Digitalis toxicity is considered as commonest cause of Bidirectional ventricular tachycardia; other causes include aconite toxicity, myocarditis, myocardial infarction, metastatic cardiac tumors and cardiac channelopathies. We describe a case of bidirectional ventricular tachycardia in a 40 year old male patient with Organophosphorus poisoning.
