Hello. Thought I had a chest infection as I was having trouble breathing. I am 50. Doctor sent me to casuality and I had a heart rate of 186. Now told I have AF and they don't know why. Still in hospital, heart working at 35%, see a different doctor every day and they question why certain medication was given the day before and then they take somethings get away or add something. No consistency and not sure when I am coming home as it keeps changing daily by every doctor. Been in for 8 days now. They are talking about a scan in about 4 to 6 weeks, then a shock the heart treatment then a possible pace maker and this is scaring me so much. Any comforting advice for moving forward as healthily as possible?
