It was reported that during the replacement procedure, the left ventricular (lv) lead had high capture threshold and high impedance measurements.It was noted that during initial manipulation of the lead the impedance measurements were normal, but after ten minutes of manipulation the impedance turned into high measurements, the capture thresholds was high and there was noise on the electrograms (egm).The lead was not used, and another lead was implanted.No patient complications have been reported as a result of this event.
