Primary Causes of Bradycardia
Bradycardia can result from problems with the heart’s natural pacemaker (the sinus node), disruptions in the heart’s electrical pathways, or underlying medical conditions such as hypothyroidism or sleep apnea. Certain medications used to treat high blood pressure or heart conditions may also slow the heart rate. Aging, heart tissue damage from a previous heart attack, or genetic factors can contribute to the development of bradycardia as well.
