It was reported that during right ventricular (rv) lead testing for an implantable pulse generator (ipg) changeout, on a patient with complete heart block, there was a delay in pacing.While doing sensing measurements, and increasing the rate to 70 beats per minute (bpm), there was a delay (hour glass), then once it went to 70 bpm, there was a delay (hour glass) before pacing resumed.The patient had a heart rate that consistently came in around 30 bpm.In addition, while generating reports, the entire application locked up and had to be shut down twice.Following the second time of shutting down and re-booting, the keyboard would pop up on every screen including the threshold screen and between threshold decrements.It was unusable and had to be re-booted again.After this third time, it seemed to work at baseline level.The mobile programmer application remains in use.No patient complications have been reported as a result of this event.
