I was just diagnosed with a fib at my yearly physical. EKG and Echo cardiogram confirmed it. I'm now on warfarin. But I think I've had this quite awhile with heart flutters, heart pounding issues and rapid pulse even while sedentary. I'm wondering what other symptoms should I be looking for. I'm experiencing depression and extreme fatigue. Is that normal? Can any of you with experience in this condition enlighten me. Thanks.
