[Orthostatic hypotension and obstructive hypertrophic cardiomyopathy (author's transl)].
The authors relate two cases of idiopathic hypertrophic subaortic stenosis detected after orthostatic hypotension with syncope. This type of detection has not been described till now. Relations between idiopathic hypertrophic subaortic stenosis and orthostatic hypotension are debated as well as relation between IHSS and systemic hypertension which has existed previously in the two cases. It seems suitable to call up IHSS systematically before every orthostatic hypotension at least in elderly. Beta-blockers can in such cases considerably improve orthostatic symptoms.
