ECG patterns may aid CRT lead verification; leaves open diagnostic accuracy in prospective studies.
The 12-lead ECG is a valuable tool for evaluating pacemaker function and troubleshooting lead placement or capture issues in patients with cardiac resynchronization therapy.
Barold et al. (2011) conducted a review in Cardiac resynchronization therapy. 12-lead electrocardiogram was evaluated. The 12-lead electrocardiogram is useful in evaluating cardiac resynchronization therapy, where a negative QRS in lead V1 during biventricular pacing often indicates lead malfunction or misplacement.
