Is ventricular electrical delay (QLV) associated with reverse remodelling and quality of life in patients receiving cardiac resynchronization therapy?
Acute measurements of QLV may be useful to guide left ventricular lead placement during CRT to optimize reverse remodelling and quality of life.
Electrical dyssynchrony, as measured by QLV, was strongly and independently associated with reverse remodelling and QOL with CRT. Acute measurements of QLV may be useful to guide LV lead placement.
Gold et al. (Mon,) studied this question.
