Performed by clenching one's fist forcefully for a sustained time until fatigued
The handgrip maneuver is performed by clenching one's fist forcefully for a sustained time until fatigued. Variations include squeezing an item such as a rolled up washcloth.[citation needed]
Mitral valve prolapse: The click and the murmur of mitral valve prolapse are delayed because left atrial volume also increases due to mitral regurgitation along with increased left ventricular volume.[5]
The effect of reducing the intensity in forward flowing murmurs is much more evident in aortic stenosis rather than mitral stenosis. The reason for this is that there is a larger pressure gradient across the aortic valve.[6] A complementary maneuver for differentiating disorders is the
Valsalva maneuver, which decreases preload.[7]
