A big combo of things. First, Getting on a beta blocker that tremendously helped my heart rate. After I did that, slowly building up tolerance to sitting for longer periods and getting up and standing again(I was bedridden for a year) breathing exercises, keeping a low stress life style(a big key for me)getting enough salt and water is another big one, taking 300-400 mg of magnesium a day(I take a brand called remag which bypasses the guy for absorbtion) taking vitamin d 3, and a multivitamin, eating foods with Potassium, low carb diet but not to the point of keto because that made me worse, limiting sugar, drinking a coffee that uses Swiss water method to really get the caffeine out so that it didn’t cause higher heart rate, and taking melatonin to help with sleep at night.

Atenolol and physical therapy/exercise

Atenolol and liquidIV are my gamechangers
