The customer provided patient retrospective database was reviewed by a spacelabs software lead engineer.The following information was located in the database concurrent with the reported event: the ics database contains two ecg waveforms as well as spo2 and respiration waveforms from 2:07 p.M.On (b)(6) 2015 to 7:26 p.M.On (b)(6) 2015.At 5:03 p.M.On (b)(6) 2015, transcutaneous pacing was initiated when there was a drop in heart rate to 33 beats per minute.At 5:04 p.M.The primary ecg lead was changed from v1 to ii.At 5:05 p.M.Pacemaker detection was enabled on the monitor.The monitor began to display pacemaker flags.However, the artifact generated by the transcutaneous pacemaker continued to overwhelm the patient¿s intrinsic ecg.The monitor accurately captured the ecg waveform from the patient, though the pacing pulses from a transcutaneous pacemaker were so large that they obscured the patient¿s ecg.There was no malfunction of the spacelabs monitor or command module.This report is considered final and the issue closed.
