Post exertional broad complex tachycardia in a normotensive patient: a rare presentation of phaeochromocytoma.

Phaeochromocytomas are rare cause of secondary hypertension with significant morbidity and mortality, if left untreated. Paroxysms with hypertension are considered as "textbook" presentations but atypical forms represent considerable diagnostic challenge. We report an unusual association between phaeochromocyotoma and post-exertional malignant arrhythmia in a normotensive subject.
