Pheochromocytoma with Ventricular Tachycardia as the Presenting Symptom

[Ventricular tachycardia as initial presentation of pheochromocytoma].

Pheochromocytoma presents with headache, sweating, and palpitations associated with hypertension, heart failure, and arrhythmias due to catecholamine secretion.1 The presence of sustained ventricular tachycardia (VT) has been reported rarely.2,3 We describe a case of pheochromocytoma that manifested as sustained and incessant monomorphic VT. A 47-year-old woman with diabetes and hypertension un...

Ventricular tachycardia--an unusual presenting symptom of scleroderma.

Since the earliest description of cardiac involvement in scleroderma by Heine (1926) and the subsequent emphasis on scleroderma heart disease by Weiss et al. (I943), a number of publications concerning the clinical features and pathological changes in this disease have appeared. The electrocardiographic abnormalities with or without clinical evidence of cardiac involvement in scleroderma have b...

Stress-Induced Cardiomyopathy Presenting as Ventricular Tachycardia

To the Editor, Stress-induced cardiomyopathy (SIC) (also known as ampulla cardiomyopathy, tako-tsubo syndrome, and broken heart syndrome) mimicking an acute myocardial infarction is a unique acute cardiac syndrome that appears under physically or emotionally stressful circumstances. It was first described in Japan and is typically characterized by chest pain, elevated ST-segment on electrocardi...

Ischemic Ventricular Tachycardia Presenting as a Narrow Complex Tachycardia

This report describes a patient presenting with a narrow complex tachycardia in the context of prior myocardial infarction and impaired ventricular function. Electrophysiological studies confirmed ventricular tachycardia and activation and entrainment mapping demonstrated a critical isthmus within an area of scar involving the His-Purkinje system accounting for the narrow QRS morphology. This v...
