Non-Ischemic Dialated Cardiomyopathy

Hi everyone, I'm a 61 year old male, and I was diagnosed with cardiomyopathy in late 2019, with an enlarged left ventricle, left bundle branch block, and an EF of 33%.  During this time I was fairly active, hiking, biking and cross country skiingand doing a rigorous spin class twice a week, but I would still get winded after climbing a single flight of stairs and I would occasionally get dizzy and light headed.  In August 2020, I lost consciousness and collapsed while I was walking to the kitchen.  When I came to I was crumpled on the floor in great pain as I had broken my ankle in the fall. Docs thought I had gone into V-fib, so along with fixing my ankle they installed an ICD to shock me if V-fib happens again and to help my right and left ventricles pump in unison. Now is Christmas 2020 and I feel better with less fatigue, my EF is up to 48% and I've only been shocked once so far. Maintaining moderate exercise, eating healthy and loosing weight, keeping on my meds and doing Cardiac Rehab twice a week.  I'm hopeful for further improvement and no more surprises.
