Pheochromocytoma presenting with bidirectional ventricular tachycardia
Heart, 2013A 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, 2016Bidirectional 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 induced by caffeine poisoning
The American Journal of Emergency Medicine, 2019Bidirectional 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

Bidirectional Ventricular Tachycardia Secondary to Subacute Myocarditis
Canadian Journal of Cardiology, 2013We 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, 2020Bidirectional 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.

[Bidirectional ventricular tachycardias].
Archives des maladies du coeur et des vaisseaux, 2005Bidirectional tachycardias are rare arrhythmias. Nevertheless in the sixties and seventies these arrhythmias prompted much work relating to their mechanism. Discussions about the supposed supra-ventricular origin of certain bidirectional tachycardias essentially rested on presumptive arguments based on electrocardiographic analysis.

A novel form of familial bidirectional ventricular tachycardia
The American Journal of Cardiology, 2004We evaluated a family with 30 members, 3 of whom had incessant polymorphous and bidirectional ventricular tachycardia (VT) that was electrocardiographically similar to that described in other familial polymorphic VT series; the VT was unrelated to exercise and asymptomatic. More subtle, but morphologically similar, ventricular arrhythmias were detected
