Why the study?
Is ventricular electrical delay (QLV) associated with reverse remodelling and quality of life in patients receiving cardiac resynchronization therapy?
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.
No takes yet. Share an insight, caveat, or question.
May support QLV-guided LV lead placement in CRT; leaves open whether randomized trials confirm outcome benefit.
Gold et al. (2011) studied this question.
