Having bradycardia (say bray-dee-KAR-dee-uh) means that your heart beats very slowly. For most people, a heart rate of 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.Or it could be a sign of a problem with the heart's electrical system.ealthy young adults and athletes often have heart rates of less than 60 beats a minute. In other people, bradycardia is a sign of a problem with the heart's electrical system. It means that the heart's natural pacemaker isn't working right or that the electrical pathways of the heart are disrupted.
More commonly, we just call this a heart attack. When the blood supply is cut off to the heart, the heart muscle doesn't receive oxygen, resulting in injury. So, just like an injured athlete slows down, so too does an injured heart. Another cause of bradycardia is hypertension, or high blood pressure. High blood pressure makes it very difficult for your heart to push blood out into circulation and causes a reflex in your body (called reflex bradycardia) that slows down the heart in order to try and lower the blood pressure.
