A 58‐year‐old man had a bipolar epicardial left ventricular (LV) implanted for cardiac resynchronization therapy after a failed transvenous approach. The system was programmed in an LV tip‐right ventricular coil configuration, but during follow‐up loss of LV capture with recurrence of symptoms occurred. Changing to an LV tip‐LV ring configuration restored LV pacing through anodal capture. Loss of cathodal capture was caused by dislodgment of the cathodal electrode due to a broken fixation suture. Anodal capture was used to reinstall resynchronization therapy, which resulted in clinical improvement. There were no adverse effects from anodal stimulation in a follow‐up period of 6 months.
