I am 62 years old, 6ft 2in and 290 pounds. I have chronic A-Fib for 5 years, non symptomatic. For one week now I have been feeling the blood flow, pulsing, in my left upper chest with some pain, but not constant. I am taking a mild blood pressure medicine (losartan-hctz) and coumidin with BPs of 150 / 95. What do you think? Thank you.
