calculated heart left ventricle end-diastolic diameter heart left ventricle end-diastolic diameter to body weight ratio heart left ventricle end-diastolic internal dimension index LVIDId sjwang LV internal dimension index diastole VT:0010758 heart left ventricle end-diastolic dimension to body weight ratio A calculated measurement in which the heart left ventricle end-diastolic internal diameter is divided by the weight of the body, and the result presented as a ratio, fraction, quotient or percentage. Heart left ventricle end-diastolic internal dimension is the diameter across the left ventricle of the heart at the end of diastole, that is, when the heart muscle is maximally relaxed, and usually corresponds to its largest diameter.
