High heart rates during paroxysmal atrial fibrillation: continuous rhythm monitoring data of the RACE V study

HeartPublished Secondary analysis of the RACE V study

Authors' conclusion

Continuous rhythm monitoring revealed that more than a third of PAF patients had heart rates above 110 bpm for more than half of their time in AF.

Study context

Population
Patients with paroxysmal atrial fibrillation (AF) with ≥1 year of continuous rhythm monitoring and an AF episode

Primary endpoint
Heart rate during PAF episodes; AF duration above heart rate cut-offs
Methodological detailsobservational, continuous rhythm monitoring, implantable loop recorder monitoring
  • Observational, continuous rhythm monitoring
  • Implantable loop recorder monitoring
