Hand grip maneuver:死命握拳动作的动作 当我们握紧拳头的时候,肌肉就会挤压外周的小血管造成血管顺应性被动降低,进而血压上升。直接结果就是左室的后负荷变大,血都出不去了,于是随之撑开左室,相对“缓解”了左室流出道梗阻的现象,肥梗心的murmur就下降了。但是其他的反流性杂音就会因为后负荷的增大而更容易反流,...
Valsalva maneuver leads to reduction in ventricular end-diastolic volume and stroke volume. This causes a worsening of the leftventricular outflow tractnarrowing and obstruction, resulting in a louder murmur. The second

In HCM, Valsalva maneuver leads to reduction in ventricular end-diastolic volume and stroke volume. This causes a worsening of the left ventricular outflow tract narrowing and obstruction, resulting in a louder murmur. The second exception is MVP, in which reduction in preload leads to early ...
