Pressor and depressor responses to tilting in hypertensive patients

The responses of intra-arterial blood pressure to passive head-up and head-down tilting are described for 50 patients with well established hypertension and compared to results obtained in subjects with normal cardiovascular systems. This study indicates that abnormal depressor and pressor responses...

Description
Summary:The responses of intra-arterial blood pressure to passive head-up and head-down tilting are described for 50 patients with well established hypertension and compared to results obtained in subjects with normal cardiovascular systems. This study indicates that abnormal depressor and pressor responses are present in many patients with hypertension, that depressor reflexes are independent of pressor reflexes, that marked variations of depressor and of pressor reflex activity occur between hypertensive patients, but that the combination of depressor-pressor responses in a given patient usually remains constant.
