Ultrasonic determination of left ventricular wall motion in normal man. Studies at rest and after exercise.

Abstract The analogue presentation of the echocardiogram was used to measure parameters of left ventricular wall motion in 25 normal males at rest and in 20 individuals after moderate exercise. Characteristic tracings of posterior wall motion, recorded by this technique, are discussed with relation to ventricular pressure and geometric events during the cardiac cycle. Following exercise, significant increases (p
