Bidirectional ventricular tachycardia induced by caffeine poisoning

American Journal of Emergency Medicine, 2019
Bidirectional ventricular tachycardia (BVT) is a tachyarrhythmia characterized by 180-degree beat-to-beat alteration in the QRS axis. BVT is traditionally known as an electrocardiography (ECG) finding pathognomonic of digitalis poisoning and a hallmark of catecholamine-induced ventricular tachycardia. Apart from digitalis poisoning, aconitine poisoning

Familial bidirectional ventricular tachycardia.

European heart journal, 1991
The occurrence of incessant ventricular arrhythmia with bouts of polymorphous and bidirectional ventricular tachycardia is described in two totally asymptomatic sisters, with structurally normal hearts and no QT prolongation. Familial survey revealed the occurrence of increased ventricular ectopic activity in the father, brother and another sister.

Bidirectional ventricular tachycardia and channelopathy

The American Journal of Cardiology, 2003
Based on similarity of electrocardiographic features, bidirectional ventricular tachycardia has been considered a variant of long QT syndrome. Genes causing long QT syndrome were used as candidate genes in 4 patients with bidirectional ventricular tachycardia.

Pheochromocytoma presenting with bidirectional ventricular tachycardia

Heart, 2013
A 44-year-old female subject was referred to our centre with recurrent hypertensive crises. Abdominal ultrasound revealed a right adrenal mass confirmed also on abdominal CT. Urine catecholamines were elevated and pheochromocytoma was diagnosed. During one of the hypertensive episodes the patient reported palpitations and a wide complex tachycardia ...

An Unusual Etiology for Bidirectional Ventricular Tachycardia

Canadian Journal of Cardiology, 2016
Bidirectional ventricular tachycardia is a rare variety of tachycardia with a morphologically distinct presentation. The QRS axis and/or morphology alternate in the frontal plane leads. We report a patient with bidirectional ventricular tachycardia in association with aconitine poisoning.

Bidirectional Ventricular Tachycardia Secondary to Subacute Myocarditis

Canadian Journal of Cardiology, 2013
We report a case of subacute myocarditis with severe heart failure referred for urgent cardiac transplantation. The patient had an episode of bidirectional ventricular tachycardia during the acute admission. Subacute myocarditis should be added to the limited differential diagnosis of bidirectional ventricular tachycardia.

PHEOCHROMOCYTOMA PRESENTING AS BIDIRECTIONAL VENTRICULAR TACHYCARDIA

Journal of the American College of Cardiology, 2020
Bidirectional ventricular tachycardia (VT) is a rare arrythmia that can occur in states of intracellular calcium overload, most commonly with digoxin toxicity, but also can be seen in catecholaminergic polymorphic VT.
