calculated heart left ventricle end-diastolic diameter heart left ventricle end-diastolic diameter to posterior wall thickness ratio 2020-06-25T17:26:40Z A calculated measurement in which the heart left ventricle end-diastolic internal diameter is divided by the posterior wall thickness, 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.
