Pheochromocytoma with uncommon ECG presentation

Pheochromocytoma is a rare neuroendocrine tumour with a highly variable clinical presentation. It may present with unusual presentation and these tend to mislead the physician into a delayed diagnosis. Typical cardiac manifestations include ST-segment deviations mimicking myocardial infarction, QT interval prolongation, blood pressure fluctuations, arrythmias mostly tachycardia but rarely may present with bradyarrythmia. We describe a case of pheochromocy-toma with rare findings of Intermittent AV dissociation associated with Junctional and ventricular ectopic rhythm.
