Left ventricular systolic torsion and early diastolic filling by echocardiography in normal humans.


This study describes a novel 2-dimensional echocardiographic technique to measure left ventricular (LV) systolic twist in humans and relates this measure to early ventricular filling. LV twist is the counterclockwise rotation of the left ventricle during systole when viewed from the apex. The effect of ventricular twist has been postulated to store… (More)
