My mother is 77 years old and has "A" fibulation. In the past 4 days she has been sleeping day and night. I am getting really worried. She says she feels fine, and that she is just tired. What do you tjink is wrong?

A fib means she has an irregular heartbeat and this increases the risk of stroke. We can't diagnose on AMHD mainly because it can't be done on the internet. I suggest you get her as soon as possible to a healthcare professional.
