Targeted left ventricular lead placement in biventricular pacing for heart failure: a national, multicentre, double-blind, randomised controlled trial in Denmark.

Left ventricular lead position is a key determinant of optimal biventricular pacing for heart failure.

Left ventricular lead position is a key determinant of optimal biventricular pacing for heart failure. Observational data indicate better outcomes in patients with late myocardial activation at the left ventricular lead site. We aimed to test whether targeting the left…
