It was reported that the right atrial (ra) lead exhibited high, out-of-range pacing impedance measurements measuring 2,200 ohms and high thresholds measuring 2.7v.It was noted that impedances and thresholds have been rising over the last year.Subsequently, a lead revision was performed and upon opening the pocket the ra and right ventricular (rv) leads were braided together.The ra lead was explanted and removed successfully.The ra lead is expected to be returned for analysis.No additional adverse patient effects were reported.
