Bradycardia - Symptoms and causes - Mayo Clinic
Dec 13, 2024 · In a typical heart rhythm, a tiny cluster of cells at the sinus node sends out an electrical signal. The signal then travels through the atria to the atrioventricular (AV) node and then passes into the ventricles, causing them to contract and pump out blood. Bradycardia can be caused by: Heart tissue damage related to aging.
