If you have bradycardia (brad-e-KAHR-dee-uh), your heart beats fewer than 60 times a minute. Bradycardia can be a serious problem if the heart doesn't pump enough oxygen-rich blood to the body.

Know your numbers. Medical experts also agree that a lower resting heart rate can indicate more efficient heart function and cardiovascular fitness, as highly conditioned athletes typically have a resting heart rate of 40 to 60 bpm.

Sometimes our hearts beat slower than 60 beats per minute. This is called bradycardia. For some people, like athletes and healthy, young adults, this heart rate could be normal. But for others, it could be a sign that your brain and other organs aren't getting enough oxygen to function like they should.
