Event Description
|
It was reported that during preparation for a magnetic resonance imaging (mri) procedure, the mri access application was used to program the cardiac resynchronization therapy defibrillator (crt-d) to the mode used for mri procedure, and the patient rate dropped to forty beats per minute (bpm) which is below the crt-d programmed lower rate setting. the patient was noted to be experiencing diaphragmatic stimulation while the left ventricular (lv) lead is in use. an attempt was made to use the programmer to set the crt-d to the mode used for mri procedure and observed that when programmed to pacing in the atrium and ventricle mode, patient rate dropped to forty bpm when programmed to eighty bpm. it was confirmed that the patient experienced stimulation with atrial paced events.Additionally, when the crt-d was programmed to pacing in the ventricle mode at eighty bpm, the patient rate was fine at eighty bpm.It was indicated that stimulation with atrial paced events and the rate dropping when the crt-d programmed to pacing in the atrium and ventricle mode at eighty bpm, suggest some type of lead issue. the crt-d and lv lead remain in use. no further patient complications have been reported as a result of this event.
