It was reported that a right atrial (ra) lead replacement procedure was performed.A new ra lead was implanted, and data measured using a pacing system analyzer (psa) was appropriate.The new lead was connected to the existing implantable cardioverter defibrillator (icd) device.The impedance and threshold measurements, as measured using a programmer, were appropriate but there was no atrial sensing observed.The lead was disconnected from the device header port and measured again using a pacing system analyzer (psa) with appropriate results.The lead was again connected to the icd device and the lead terminal pin was confirmed to be fully and securely inserted into the device header port.Again, programmer measurements exhibited no atrial sensing.The lead was once again disconnected and reconnected to the device header port, but the condition did not improve.As a result, the icd device was explanted and replaced with an icd device of the same model number prior to pocket closure.The procedure was successfully completed.No additional adverse patient effects were reported.
