Abstract

Compensated cardiac patients, like normal subjects, on performing the Valsalva maneuver show a decrease in systolic, diastolic, and pulse pressures during the blowing effort and a characteristic hypertensive overshoot after the release of the strain. Cardiac patients in congestive failure show the "failure response" with a maintenance of the systolic, diastolic, and pulse pressures during the expiratory strain and an absence of the overshoot afterwards. Experimental and clinical observations in patients indicate that this "failure response" is due to elevation of the right ventricular diastolic pressure, which interferes with the normal obstruction of venous return during the blowing effort of the Valsalva maneuver.
