It was reported that there is concern using the newest model external pulse generator (epg) during electrocautery/ablation procedures.The concern was due to a configuration, which was present in the previous model, having been removed from the programming options.This current configuration mode can result in asynchronous dual chamber pacing and in certain modes can prevent t-wave pacing.It was also noted that this model switches from ddd mode to a vvi protection/backup mode, which is an undesirable mode during induced oversensing and also when the patient has an intrinsic normal atrial ventricular (av) conduction.When the emergency mode is pressed, all outputs are maximized and need to be reduced manually or health professionals are not fast enough to switch to this emergency mode.Specific model numbers, dates and patient information were unable to be provided as the health care profession provided this information past the purported incidents; however, in no case was it suggested that the epg malfunctioned or did not perform as designed; rather the concern is that the mode configuration could place the patients at risk during electrocautery/ablation procedures.The status of the epgs is unable to be determined.No further patient complications have been reported as a result of this event.
