During a pacemaker lead removal procedure in a patient with complete av block, the catheter was inserted into right ventricular for backup pacing.The catheter paced intermittently and when the permanent lead was removed, the catheter did not pace resulting in 15 seconds of asystole.The catheter was replaced with a non-abbott device and the procedure was completed with no further consequences to the patient.

One 5f pacel bipolar pacing catheter was received for analysis.The results of the investigation concluded there were intermittent signals and high resistance between the ring electrode and proximal (+) connector pin, however, the cause of the intermittent and high resistance could not be determined.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed.The cause of the pacing issue is consistent with the intermittent signals and high resistance.The cause of the intermittent signals and high resistance remains unknown.
