I have no idea why I had this appointment, and the nurse and doctor were as confused as I was! When I came for my device check last time, the technician sat me an appointment up with the new doctor, Dr. T, so it was a waste of my time and Dr. T, and $30.00 copay! We did discuss the battery life of my defibrillator!
