I have cardiomyopathy caused by medication which I have to stay on, no other choice. Dr wants to install a subcutaneous difib and says Im heading for a heart attack. Cant have a implanted difib/pacemaker. Question, when I have a heart attack and the defib revives me, hopefully, what happens next? Im taking medication and nothing will change about the med thats causing the problem. Do I just keep having attacks until Im not revivable or what? My cardiologist just looks at me when I ask. Im taking magneseum and other minerals, which have helped with arry and palps.
