NCT02442505

Brief Summary

This study will use an automated blood pressure monitor (Microlife WatchBP03) with an inbuilt algorithm to detect atrial fibrillation (an irregular heart rhythm) in patients with an implanted pacemaker who have previously documented paroxysmal (intermittent) atrial fibrillation. This study will compare the Microlife device detected atrial fibrillation episodes to the pacemaker detected atrial fibrillation episodes.

Outcome Measures

Primary Outcomes (2)

  • Percentage of patients who are identified as having atrial fibrillation by both the pacemaker and the Microlife device (%)

    True positive rate (sensitivity)

    24 hours

  • Percentage of patients who are identified as not having atrial fibrillation by both the pacemaker and the Microlife device (%)

    True negative rate (specificity)

    24 hours

Interventions

Microlife WatchBP03 device which is an automated oscillometric device using a new algorithm to detect atrial fibrillation

Sampling MethodProbability Sample
Study Population

Patients who have an implanted pacemaker for sick sinus syndrome with previously documented AF with atrial high-rate episodes, with be identified from the pacemaker clinic register at one NHS Trust. Patients with AF and one of the following pacemakers will be identified from this register: Medtronic Sensia DR, Medtronic Advisa DR, Sorin Reply DR, and St. Jude Medical Accent DR and the study population will be randomly drawn from these patients. Atrial high rate episodes will be defined as atrial rates ≥180 beats per minute \[3-6\]. The exclusion criteria will include any patient who's pacemaker has had previously documented atrial sensing or pacing problem issues and patients with permanent AF.

You may qualify if:

  • Patients with an implanted pacemaker for sick sinus syndrome with previously documented AF with atrial high-rate episodes

You may not qualify if:

  • Any patient who's pacemaker has had previously documented atrial sensing or pacing problem issues
  • Patients with permanent AF
