My 53 yr old brother was admitted to the CCU with 277 heart rate May 20th. We were told his heart was functioning at 15%. After catheterization, dr. said his heart was great inside but that it was grossly enlarged, "about the size of a cow's heart". Because he was out of rhythm, they also performed an ablation which was successful. He also had chest tubes in and lost 40 lbs during the 2 weeks he was in the CCU. He is now home, but because he lives alone, he wears a LifeVest defibrillator. He needs to lose weight, he is approx 230 lbs and is 5'9''. He sleeps well, but is very fatigued after about 4 hours awake. His other organs are great, his heart rate is back to normal, but where do we go from here? His line of work was welding in a heavy machine shop in Florida. I live in New York. What questions should we be asking his cardiologist. I know his condition is very serious and I want to help him.
