One hundred thirty-three subjects were examined to evaluate a quantitative system for grading the cardiac apical impulse and to compare palpatory findings supine versus the left lateral decubitus position (LLDP). Impulses were graded from 1 to 4 in both force and duration by simultaneous auscultation and palpation. Those with force and duration of 2 or less were found primarily in normals and were designated physiologic. The remainder were divided into sustained (duration 3 or 4) and hyperkinetic (force 3 or 4) on the basis of the dominant abnormality.
In 76 subjects over 30 years old, 32 had palpable impulses supine;
