Having bradycardia say "bray-dee-KAR-dee-uh" means that your heart beats very slowly. For most people, a heart rate of 60 to 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. For some people, a slow heart rate does not cause any problems.
It can be a sign of being very fit. Healthy 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.
Sometimes, the heart beats so slowly that it doesn't pump enough blood to meet the body's needs. This can cause symptoms, such as feeling dizzy or weak. In some cases, it can be life-threatening.
Some people don't have symptoms, or their symptoms are so mild that they think they are just part of getting older. You can find out how fast your heart is beating by taking your pulse. If your heartbeat is slow or uneven, talk to your doctor. Your doctor may take your pulse to diagnose bradycardia. Your doctor might also do a physical exam, ask questions about your past health, and do an electrocardiogram EKG or ECG.
An EKG measures the electrical signals that control heart rhythm. Bradycardia often comes and goes, so a standard EKG done in the doctor's office may not find it. An EKG can identify bradycardia only if you are actually having it during the test. You may need to wear or carry a device called a portable, or ambulatory, electrocardiogram.
Examples include a Holter monitor and a cardiac event monitor. You might use it for a day or more. It records your heart rhythm while you go about your daily routine. How bradycardia is treated depends on what is causing it. But there are exceptions. Your heart rate may fall below 60 BPM during deep sleep. And physically active adults and athletes often have a resting heart rate slower than 60 BPM.
