title: [Semiological value of the electrocardiogram in pheochromocytoma].
abstract: ECG abnormalities of various types and extent were noted in subjects with pheochromocytoma. In the majority of cases, they regressed after surgical resection of the tumour. The underlying pathogenetic mechanisms are discussed in the light of the functional and organic cardiac and vascular alterations induced by the abnormal increase in catecholamines. Reference is also made to the literature in support of the diagnostic and prognostic soundness of ECG with regard to both pheochromocytoma and any heart involvement it may cause.
