[Effect of isometric force (handgrip) on R wave amplitude].
We have measured R-wave amplitude during isometric stress-handgrip test in 30 normal subjects, without finding any significative variation. We believe, in according to our angiographic and echocardiographic experience, that such a behaviour is due to the absence of heart volume modification during handgrip test.
