fractional shortening

fractional shortening

The reduction of the length of the end-diastolic diameter that occurs by the end of systole. Like the ejection fraction, this is a measure of the heart's muscular contractility. If the diameter fails to shorten by at least 28%, the efficiency of the heart in ejecting blood is impaired.

Left ventricular fractional shortening was calculated by the following formula: [left ventricular-end diastolic diameter (LVDD)--left ventricular-end systolic diameter x 100]/LVDD.
