High prevalence of cardiac electric abnormalities in patients with phaeochromocytomas
Phaeochromocytoma and sympathetic paragangliomas are rare catecholamine-producing tumours arising from the adrenal medulla or extra-adrenal sympathetic paraganglia. Phaeochromocytoma was labelled as a disease with ‘multiple faces’ due to its highly variable clinical presentation . Some patients may be asymptomatic, whereas in others, phaeochromocytomas are associated with major cardiovascular manifestations . In addition to hypertension, catecholamine excess can be at the origin of cardiac arrhythmias, myocardial infarction, haemodynamic collapse, heart failure, pulmonary oedema and cardiac arrest .
