the heart is monitored by ECG, pressure recording, or other methods while the patient performs the Valsalva maneuver; carciac volume decreases in unaffected patients but may dilate in the patient with impaired myocardial reserve; there is a characteristic complex sequence of cardiocirculatory events, departure from which indicates disease or malfunction.

Valsalva sinus - the space between the superior aspect of each cusp of the aortic valve and the dilated portion of the wall of the ascending aorta. Synonym(s): aortic sinus
Valsalva test - when the heart is monitored during the Valsalva maneuver, there is a characteristic complex sequence of cardiocirculatory events, departure from which indicates disease or malfunction.
