Going from a stable 50-60 beats per minute to over a hundred beats per minute. She had been stabilized for over a year, and she had been having some issues with retaining too much water. The doctor prescribed a special diuretic to use when her usual one didn't keep her water weight down. I feel that she let it go too far, and now her A-fib is out of control again and her heartrate has been in the 90-119 range for the last two weeks. The doctor seems to be taking a cautious approach and while he doubled her amiodarone he has cut it back down and she still is having the high heart rate with some irregular beats. The home health nurse comes once a week and she contacts the doctor if she feels that he needs to assess what is going on. I am concerned and worried about how long she can go on like this. Has anyone else had these issues and how did you handle them?
