After its return, the pacemaker underwent a status interrogation, and the memory content was analyzed.The analysis of the memory content showed proper device behavior.In a next step, the pacemaker was visually inspected, and the connection system was examined.Minor damage was found at the plate screw, as well as a slightly rounded thread of the plate screw.This indicates the impact of a strong external force during the operation.The plate screw could be tightened without problems during the analysis.The screws and the spring elements of the lead connections were without defects.Leads inserted as a test could be contacted with easy passage, low-ohm values, and reliably.The drill hole dimensions were all within the dimensions defined by the is-1 standard.The pacemakers capability to provide therapy was tested.The antibradycardic output signal matched the programmed values, and the signal sensing of the device was normal.The pacemaker showed specification-conforming behavior in regard to its device functions.In summary, the device was without defects during the analysis and within specifications both regarding the connection system and the electronics.There was no material defect or manufacturing error.
