Bradycardia: What Does It Mean When Your Heart Rate Is Below 60?

Normal heart rate, known as sinus rhythm, typically ranges between 60 and 100 beats per minute (BPM). When the heart rate drops consistently below 60 BPM, it is referred to as bradycardia, or sinus bradycardia. However, for many individuals, especially those who are physically active or athletes, a heart rate slightly below 60 BPM—often around 50 BPM—is considered normal and healthy.

Understanding the Causes of Low Heart Rate

Several factors can contribute to a slower heart rate. Regular physical activity strengthens the heart muscle, allowing it to pump more efficiently and maintain a lower resting heart rate. However, when bradycardia occurs in individuals who are not physically trained, it may indicate an underlying health condition.

Symptoms of Severe Bradycardia

If the heart rate drops significantly, such as to 30-40 BPM during the day, it can lead to serious complications. Common symptoms include dizziness, fatigue, shortness of breath, and even fainting or near-fainting episodes. These signs suggest that the heart may not be pumping enough blood to meet the body's needs.

When to Seek Medical Attention

It is crucial to seek immediate medical care if you or someone you know experiences severe bradycardia along with noticeable symptoms. This condition could be caused by issues with the sinus node or atrioventricular node, which are responsible for regulating the heart's electrical signals. These types of heart rhythm disorders can be serious and require prompt diagnosis and treatment to prevent further complications.
