I am a healthy 55 year old male. I have a resting heart rate of 38 for a long as I can remember. About 2 years ago I experienced dizziness and was diagnosed with mediated hypotension . I take florenef to raise my blood pressure. I have have no symptoms related to my bradycardia . My primary care doctor took an EKG and said it is a concern if I have a resting heart rate of 38 while at the office. She told me if I were sleeping it would be exceptable. My cardiologist said I would eventually need a pace maker but if I'm not symptomatic I should not worry. My question is should I worry? Is there a danger? What should I do?
