Factors that affect atrial tracking and atrial fibrillation in people receiving the Micra AV2 pacemaker
Official title: Determinates of Atrial Tracking and Prevalence of Atrial Fibrillation in the Micra AV2 (DANCE AFIB)
Run by Northwell Health · NCT07344961 · Data updated 2026-11-12
This will see how well the Micra AV2 device tracks atrial activity and how often short episodes of paroxysmal atrial fibrillation occur in adults who receive the device.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are English-speaking adults aged 18–85 with a history of paroxysmal atrial fibrillation who are receiving a Micra AV2 pacemaker per standard clinical care and can attend follow-up.
✕Probably not a fit
Patients with persistent or chronic atrial fibrillation, those unable to complete follow-up, or those enrolled in conflicting device/drug studies are unlikely to benefit from the study's findings.

What this trial studies
This prospective, descriptive observational study enrolls adults with a history of paroxysmal atrial fibrillation who are receiving a Micra AV2 pacemaker as part of standard care at Northwell Health. Investigators will perform periodic device interrogations and use a designated Medtronic research Holter monitor to capture Micra AV2 signals during sinus rhythm and during episodes of atrial fibrillation. The study will track the presence and effectiveness of atrial tracking, including atrial activity and A4 amplitude trends, over time but will not include formal safety endpoint assessments. Patients with persistent or chronic atrial fibrillation are excluded, and enrollment is limited to consenting English-speaking adults aged 18–85 who can complete follow-up.
Why it matters
Potential benefit: If successful, the results could help doctors identify which patients are most likely to get reliable atrial tracking from Micra AV2 and improve device programming and follow-up.
How similar studies have gone: Previous studies of Micra AV devices have shown that mechanical atrial sensing can work in many patients, but Micra AV2-specific data on atrial tracking in paroxysmal atrial fibrillation remains limited.
