While a "resting heart rate below 40, with average at 47" may be normal for you, obtain a referral to a cardiologist for an evaluation and further monitoring via a Holter counter for reassurance.

I agree you should not be dismissed by being told you have high vagal tone. Did your EKG show simple sinus bradycardia? Does your heart rate accelerate appropriately with physical activities? Heart rate under 40 at night is concerning. The Holter Monitor will provide important information. With very slow heart rates stroke volume of the heart rises to compensate causing elevated BP. ?pacemaker n
