The reported field event of lead connection issue was confirmed.The device was above elective replacement indicator (eri) when received.Analysis revealed the rv (df4) set screw was backed out from its thread as a result of unscrewing the set screw too far.When the screw was re-engaged with the connector block, the screw operated normally in affixing the test lead to the header.The connection anomaly was consistent with having occurred during the procedure.Telemetry, impedance, sensing, pacing and high voltage (hv) output functions of the device were tested and found to be normal.
