A case of orthostatic and postexertional hypotension with ischemic electrocardiographic changes.
A case of orthostatic and postexertional hypotension with ischemic electrocardiographic changes is reported. The etiology was considered to be the partial dysfunction of efferent sympathetic nerve endings. Peripheral adrenergic receptors (alpha and beta) were up-regulated, which might have caused pseudoischemic electrocardiographic changes and abnormal vasodilation after exercise.
