ΔLVEF = (LVEF 6 months after CRT implantation) - (LVEF before CRT implantation)
ΔLVESV = (LVESV 6 months after CRT implantation) - (LVESV before CRT implantation)
The rate of decrease in LVESV = (LVESV reduction)/(LVESV before CRT implantation)
LVEF: Left Ventricular Ejection Fraction; LVEDV: Left Ventricular End-Diastolic Volume; LVESV: Left Ventricular End-Systolic Volume; ASQ: Attain Stability Quad
