Took 7 years and a lousy 2009/2010 but finally came up with something to stop my Afib. Magnesium citrate(also taking calcium). Am taking 200mg 3x per day. No a fibs since September 16th. and i was getting 2 episodes or more per month. The past year I got so bad had to quit biking, i would go into A-fib every time i went up hill. Sleep deprivation is my trigger. Like getting up at 5:30 to train....so looked up sleep deprivation and electrolytes, and guess what? It lowers magnesium and calcium. Try it . Worked for me. Calc. citrate and Magnesium citrate are absorbable and cheap. Dont take mag oxide or calc. carbonate- not absorbable. Happy training!
