My EF was 12 when I got mine. I had been very sick and so weak. The procedure to implant the device wae simple and relatively painless. I felt better immediately. It's been over 8 years now and I have nothing bad to say. When I get out of breath I recover very quickly. I named my device Agadore and am glad to hear him aboard. Hope this helps you in some way. 🤠

I have had 2 with defibrillator. There were some problems with the Dr but saved my life 3 times, always in my sleep. Have you asked your Dr to be specific and detailed? If he won't time for a second opinion!
