In July of 04 I was diagnosed with hypertrophic cardiomyopathy, with a 15 - 20% ejection fraction. I also have CHF and COPD. I had my ICD implanted in February of 06. I felt like a whole new person at first. I received my first shock about 8 months ago so they raised me to 180 threshold. Again, I felt great. For the last 2 months I have been very tired, I never feel good and I get these sensations in my chest that feel like I am going to have an anxiety attack but they go away after a few minutes. I also have alot of sinus problems and don't know if this contributes to these feelings. I would think that they wouldn't. I am prescribed Valium, 5 mg, but I only take them when I need to. I don't like being down and do all that I can to lead a normal life. Although I had to quit my job because of my ejection fraction and my doctor's will not let me work. They say that I need to rest rest rest. I am wondering if anyone else has had a problem with pain in their chest, feelings of anxiety and impending doom and, in general, just not feeling good. I am tired of feeling bad. I tend to sleep alot now. I am not depressed. I just do not feel good anymore. Is there anyone in this forum that feels like I do? What is it and what can be done about it?
