Study Notes

  • Removing reversible causes is the initial strategy in treating symptomatic patients with sinus node disease.
  • Medications such as beta blockers, calcium channel blockers, and digoxin should be eliminated if they are causing bradycardia.
  • Treatment of tachycardia can prevent bradycardia events, which can be achieved through antiarrhythmic drug therapy or catheter ablation.
  • Reversal of ischemia with revascularization can alleviate bradycardia in some cases.
  • Transient sinus node abnormalities may occur due to acute illness associated with episodes of extreme vagal tone.
  • Sinus bradycardia is common after heart transplantation, cardiac surgery, and spinal cord injury.
  • Permanent pacing is indicated to alleviate symptoms of bradycardia in SA nodal disease.
  • There is no established heart rate below which pacemaker treatment is indicated.
  • Asymptomatic sinus bradycardia does not typically warrant permanent pacing.
  • Consensus guidelines published by the American Heart Association outline the indications for the use of pacemakers.
