Impact of Q wave in synthesized V7–9 lead on long-term outcomes after cardiac resynchronization therapy

To investigate the relationship between the Q wave in synthesized V7–9 leads of a baseline electrocardiogram and clinical outcomes in patients with heart failure after cardiac resynchronization therapy (CRT) device implantation. Consecutive patients with heart failure and a left ventricular (LV) eje...
