Like HCM, everyone is different. I find that those that are otherwise healthy, active, and in shape will have a shorter recovery than someone who isn’t. For me, I was a 50 year old gym rat who exercised 1-2 hours a day. I had no complications (in hospital or at home). I went back to work full time at around 7 weeks. Mainly due to boredom. It’s important to rest, sleep, walk and do your breathing exercises. Once Home, I took walks 3 times a day, first just to the mail box, then to my neighbors mail box, then a few houses, a block, several blocks (you get the picture). Careful not to overdo it. There will be days you can do more, and days you will do less. If, after a good day & you’re exhausted the next day, you over did it.
Listen to your body.
