I can empathize with you Deya, re: those hospital beds and ruining your tail bone. Not enough to worry about our heart, but, after almost 2 weeks in the hospital very recently, my derrière still is not the same. I hope you get 1st rate treatment for your heart. Get these things early and your chances are great.
At almost 93 yrs, I have 6 doctors treating me for what is now called Atypical A-Flutter. Not as bad as A-Fib, but close. But, I've had heart trouble on and off due to hypertension for many years.
In addition, thought, this last hospitalization also had to deal with a double pneumonia. Never let it be said, I do things 1/2 way. Amazingly, I am here to tell about it.
Be well.
