Event Description
|
It was reported that the patient received an inappropriate shock from the cardiac resynchronization therapy defibrillator (crt-d) while a cream warming device was being used during a massage.It was noted that prior to the shock the interference was present an caused two lead different very low near zero lead impedance measurements.The crt-d remains in use. no further patient complications have been reported as a result of this event.
