I have a resting heart rate of about 37. Rarely leaves the 30's except on exercise. My doctor is worried and ordered blood and other tests--all normal and a very healthy heart. I am a very moderate runner at present, do 5k runs (or cycling) three x a week. At 50 yrs. old (female) have been running for 25 years, sometimes 5 x a week. Anyone else for very low resting rate? Do you feel o.k.? I feel better after runs (more energy, warmer), when my resting rate goes up and stays up for a few hours. Is this normal for others of you out there? Thanks for your input.
mine's in the 40's...... No one was worried. I run about 30 mpw and bike 40.... I found this http://www.fitsugar.com/Low-Resting-Heart-Rate-94359 It might comfort you to know the article state UNDER 30 is cause for alarm.
Technically, low resting heart rate is called Bradycardia, defined as a resting heart rate under 60. But it is not uncommon for athletes to have resting heart rates below 60. Mine is around 48 (at age 62). In fact, while I was sitting on the table, all hooked up and waiting for my last stress test, my heart rate was 50. The Wikipedia article on Bradycardia says "Trained athletes or young healthy individuals may also have a slow resting heart rate (e.g. professional cyclist Miguel Indurain had a resting heart rate of 28 beats per minute). Resting bradycardia is often considered normal if the individual has no other symptoms such as fatigue, weakness, dizziness, lightheadedness, fainting, chest discomfort, palpitations or shortness of breath associated with it."
As the article cited above says: "The slow heart rate usually just indicates a strong heart." If you have no other symptoms, I doubt that you have anything to worry about. Still, your doctor is being cautious, which is not a bad thing.
