Bradycardia: Understanding Low Heart Rate - Symptoms & Causes

A heart rate that is considered too low is called bradycardia. In adults, a heart rate of less than 60 beats per minute is generally considered bradycardia, however, some athletes and very fit individuals may have a resting heart rate below 60 bpm without any underlying health problems. In children and infants, the normal heart rate range varies depending on age.

Signs and symptoms of bradycardia can include:

- Fatigue or weakness

- Lightheadedness or dizziness

- Shortness of breath

- Confusion or memory loss

- Chest pain or discomfort

- Syncope (fainting)

Bradycardia can be caused by a variety of factors, including:

- Heart disease, such as coronary artery disease or heart failure

- Thyroid problems

- Diabetes

- Medications, such as beta-blockers or calcium channel blockers

- Sleep apnea

- Dehydration

- Electrolyte imbalances

If you experience any signs or symptoms of bradycardia, it is important to see a doctor to determine the cause and receive appropriate treatment. Treatment for bradycardia may include lifestyle changes, medications, or a pacemaker to regulate the heart rate.
