noninvasive determination of the time intervals of aortic closure sound to mitral valve opening ( a2-mo ) , mitral d point to e point ( d-e ) , aortic closure sound to mitral e point ( a2-e ) , the interval from the onset of the qrs to mitral closure ( q-c ) , and the ratio q-c/a2-e were compared to invasive measurements of mean pcw , the height of the v wave of pcw ( pcw-v ) , and the ratio of pcw-v to left ventricular ( lv ) peak systolic pressure ( pcw-v/lv ) .
