Key result
A patient presented with bidirectional ventricular tachycardia associated with non-ST elevation myocardial infarction and severe cardiomyopathy in the absence of digoxin toxicity.
Case Report (n=1)
Highlights a rare etiology for bidirectional ventricular tachycardia, demonstrating its occurrence with NSTEMI and severe cardiomyopathy independent of digoxin toxicity.

Expands bidirectional VT differential to NSTEMI with cardiomyopathy sans digoxin; single case leaves open prevalence and mechanisms.
Bidirectional ventricular tachycardia (BVT) is a rare variety of tachycardia with morphologically distinct presentation: The QRS axis and/or morphology is alternating in the frontal plane leads. Since its original description in association with digitalis,(1) numerous cases of this fascinating tachycardia with disparate etiologies and mechanisms have been postulated. We report a patient with BVT in association with non-ST elevation myocardial infarction and severe cardiomyopathy in the absence of digoxin toxicity.
