Scorpion sting-induced myocardial damage and pulmonary oedema.

ABSTRACT

A patient with electrocardiographic abnormalities simulating early myocardial infarction after scorpion sting is reported. Pulmonary oedema and congestive heart failure accompanied these electrocardiographic changes. The aetiology of the cardiovascular manifestations in severe scorpion sting is related to the venom effects on the sympathetic nervous system and the adrenal secretion of catecholamines, as well as to the toxic effects of the venom on the myocardium.
