Detailed explanation-1: -Having bradycardia (say “bray-dee-KAR-dee-uh") means that your heart beats very slowly. For most adults, a heart rate of about 60 to 100 beats a minute while at rest is considered normal. If your heart beats less than 60 times a minute, it is slower than normal. A slow heart rate can be normal and healthy.
