The patient presented in-clinic following a vibratory alert from the device.The device was interrogated and it was revealed that the pacing impedance of the left ventricular (lv) lead was high and out-of-range.It was also observed that the capture threshold has increased on the lv lead.It was suspected that the cause of the event was due to damage to the ring electrode of the lv lead; however, no imaging was conducted to confirm the supposition.The device was reprogrammed to resolve the event.The patient was stable with no consequences.
