- Increased intracranial pressure
- High blood pressure
- Certain medications, such as beta blockers
- Certain medical procedures, such as carotid sinus massage
Symptoms
Symptoms of reflex bradycardia may include:
- Dizziness
- Fainting
- Fatigue
- Shortness of breath

Treatment
Treatment for reflex bradycardia typically involves addressing the underlying cause. This may include adjusting medication dosages, treating high blood pressure, or managing other underlying conditions.
