My heart, when they installed the ICD, was at 15%, and they haven't checked again since the surgery. However, I can tell you it has to have went up because of the way I feel. I will see my Cardiologist Aug. 26th, and he will most likely set me up for an Echo Cardiogram to check my HR.
I, now, only take 12.5 mg of Coreg once a day, along with vitamins, and 160 mg of lasix, once a day, and it's working for me. :)
I hope the very best for both of you!
