@sjm46 yes me also. I spent some time at home I seem to remember a couple of weeks as the meds got in my system. Then work was very understanding and found me some light duty work to do. But I was back to my normal job as an electronic technician working in substations on the communication equipment. Because I also just had a pacemaker installed i could not lift for 6 weeks over 10 pounds or reach over my head. The next time they did an ultrasound i was in the 30's but I cant remember how long after that was exactly. I want to say 6 months. that was in 2008. But it wasn't long before it got into the high 40's low 50's. It stayed there for most of the 10 years leading up to my transplant. The low EF was not the reason for it as due to the enlarged heart my main problem was electrical. So my bad paths got to the point that my pacemaker and meds were not keeping the arrythmias under control. I want to share that part as i was still in the 50 range leading up to the transplant. So if low EF is your main concern its defiantly possible to get back up to a close to normal level.
