I am 56 years old and was diagnosed with systolic congestive heart failure and a low ejection fraction (less than 20) in Nov 2016. They did a heart cath and said I had a virus that caused the damage. It has been 8 1/2 months and my ejection fraction has only come up to between 25 and 30. I have been wearing a lifevest since Nov and they are wanting to put in an ICD. What kind of limitations are there with that? I feel much better than I did but still have to be careful how much I try to do. I get tired easy. Any input would be appreciated. Thank you!
