Hello student here the question is given and the question is about this fractional shortening.
00:11
So this can, this is need to be monitored here and the echocardiography is given.
00:21
Echocardiography.
00:24
So this is a fractional shortening is a simply a parameter here we can say and this in order to assess the contractility to the of the left ventricle of heart.
00:55
So it is mainly calculated by a simple formula in the percentage.
01:01
So this fractional shortening in percentage is simply calculated by the left ventricular dimension or diameter minus we have to left ventricular dimension of this systolic or diameter and this is divided by this left ventricular diameter diastole into 100.
01:23
So this is the percentage value and this simply the diastole is the one which is the left when it is a maximally filled with the blood and while this is going to be the release of the blood after releasing this.
01:41
So systolic condition and the diastolic condition the contraction of the ventricle here and the different if we find these two value then we can calculate this fractional shortening.
01:55
So here the echocardiography is given and echocardiography this lv, this lv simply represent left ventricle and this left ventricle free wall and this is the left ventricle free wall while another one which is given this id left ventricle so this is the left ventricle internal diameter.
02:32
So similarly this represent this diameter and again there are the interventricular septum so this ivs is interventricular septum...
