Risk Factors

  • According to MOT trial the two variables that predict the development of pacemaker syndrome in the pre-implantation period are low sinus rate, and a higher programmed lower rate limit. In post-implantation, an increased percentage of ventricular paced beats is the only variable that significantly predicts development of pacemaker syndrome.
  • Patients with intact VA conduction are at greater risk for developing pacemaker syndrome. Around 90% of patients with preserved AV conduction have intact VA conduction, and about 30-40% of patients with complete AV block have preserved VA conduction. Intact VA conduction may not be apparent at the time of pacemaker implantation or even may develop at any time after implantation.[1]
