I was told I was a prime candidate for an ICD Implant (defibrillator). My pump rate is 50/30. My heart rate is normal and steady, but I had congestive heart failure this past summer. I am taking meds. My main concern is that I am very active and very involved in cars and hot rods. I am continuously under the hoods of cars. I was told this would have to be eliminated post procedure. Can anyone expand? I do not want to change my lifestyle.
