My husband got a new ICD (defibrillator/pacemaker). He had an EF of 35% on one side and 41% on the other, and a slight heart attack, that they said damaged the muscle. His heart rate was in the 50s. I wonder if he really needed it. He did not want it. The selling point, that if his heart stops, it would start it again.. Now we are linked (shackled?) to medtronics the rest of our lives. Did you notice that their monthly monitoring fee for the device is the same as an office visit? Nice business. So far, a week out, I felt better before the procedure.
