As a medical professional with expertise in cardiology, I can provide you with an understanding of what it means to have a low heart rate.

A low heart rate, medically referred to as bradycardia, is when the heart beats fewer times than normal in a minute. For adults, a normal resting heart rate is typically between 60 and 100 beats per minute (BPM). A heart rate below 60 BPM is generally considered low. However, it's important to note that a low heart rate is not always a cause for concern. In fact, well-trained athletes and individuals with high levels of physical fitness may have a normal resting heart rate that is lower than 60 BPM.

There are several potential causes for a low heart rate, including:


1. Increased Parasympathetic Tone: The body's natural "rest and digest" system can slow the heart rate, which is normal during sleep or relaxation.

2. Age: Older adults may naturally have a lower heart rate.

3. Medications: Certain medications, like beta-blockers, can cause a decrease in heart rate.

4. Underlying Health Conditions: Conditions like hypothyroidism or electrolyte imbalances can lead to a low heart rate.

5. Sick Sinus Syndrome: This is a condition where the heart's natural pacemaker doesn't work properly.

While a low heart rate can be normal in some individuals, it can also be a symptom of an underlying health issue. If someone experiences symptoms like fatigue, dizziness, shortness of breath, or fainting along with a low heart rate, it's important to seek medical attention.

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.read more >>
