Description

Bradycardia is caused by a disruption in the hearts electrical system that controls the heart rate. This disruption can come from four possible causes:

  • Sinoatrial node problems & the sinoatrial node, often referred to as the sinus node, is considered to be the natural pacemaker of the heart. This group of cells triggers electrical impulses to the heart, causing it to contract. When this node isn’t working properly it can trigger much slower electrical impulses causing the heart to beat slower.
  • Dysfunctional conduction pathways electrical impulses travel in the heart via conduction pathways. When these pathways do not work properly, the heart rate is affected — a condition often referred to as an atrioventricular block or of which there are three forms:
  • First degree - all of the electrical signals from the atria reach the ventricles, although they are transmitted slower than normal.
  • Second degree - only some of the electrical signals from the atria reach the ventricles. When a signal does not reach the ventricles, the heart beat it was meant to trigger does not occur.
  • Third degree - none of the electrical impulses make it from the atria to the ventricles. When this happens, a natural pacemaker in the ventricles may step in to take over regulating the heartbeat, although at a rate that is slower than normal.

Other risk factors that may contribute to a disruption of the electrical impulses associated with bradycardia include:

  • Congenital heart disease
  • Infection of the heart tissue
  • Heart surgery
  • Hypothyroidism or other metabolic condition
  • Damage caused by
  • Electrolyte imbalance in the blood
  • Obstructive sleep apnea
  • Inflammatory diseases rheumatic fever lupus
  • Certain medications

Bradycardia can affect patients of all ages, genders and ethnicities. However, older patients are at an increased risk as well as patients with the following risk factors:

  • High blood pressure
  • Smoking
  • Heavy alcohol use
  • Use of recreational drugs
  • Psychological stress or anxiety
