Overview
Pathophysiology
This rhythm may be caused by one of the following:
- Increased vagal tone
- Intrinsic disease of the SA node
- An effect of drugs, such as the use of digitalis or beta-blockers
- Sleep
- Sinus bradycardia is a normal finding in a healthy, well-conditioned athlete
The HCN4 genetic variant is associated with sinus bradycardia. Certain sodium channelopathies are associated with sinus bradycardia.[1]
