My husband was diagnosed to have A-fib in 2004. He received full work-up, Echo, ECG, ultrasound, etc. They also discovered left bundle branch block. He was cardioverted and remained in sinus rhythm. Saw a cardiologist who said all was well. Go home and try to lose some weight. He is currently on Micardis and Propranolol. He recently had a sore throat and fever. Fever subsided but sore throat is still present. He has just recently experienced symptoms of A-fib; weakness, dizziness when bending over and irregular heart. BP is normal. Should he see his doctor?
