SymptomsBy Mayo Clinic Staff
If you have bradycardia, your brain and other organs may not get the supply of oxygen they need. As a result, you may experience these bradycardia symptoms:
- Near-fainting or fainting (syncope)
- Shortness of breath
- Chest pains
- Confusion or memory problems
- Easily tiring during physical activity
When a slow heart rate is normal
A resting heart rate slower than 60 beats a minute may be normal for some people, particularly for healthy young adults and trained athletes. For these people, bradycardia isn't considered a health problem.
When to see a doctor
A number of conditions can cause signs and symptoms of bradycardia. It's important to get a prompt, accurate diagnosis and appropriate care. See your doctor if you or your child experiences any symptoms of bradycardia.
If you faint, have difficulty breathing or have chest pain lasting more than a few minutes, get emergency care or call 911 or your local emergency number. Seek emergency care for anyone experiencing these symptoms.
