clude a systolic ejection murmur that becomes in-creasingly loud during maneuvers that decrease preload (such as a change in the patient’s position from squatting to standing) and evidence of left ventricular hypertrophy on electrocardiography. The diagnosis can be confirmed by two-dimension-al echocardiography, which shows hypertrophy of

be predicted that squatting would have the opposite effect of the Valsalva maneuver. The increased preload and ejection velocity would tend to increase the Reynold’s number, the possibility of turbulence, and the intensity of the murmur. It follows that return-ing to a standing position will decrease venous return, left ven-
