Monitoring Atrial Fibrillation After ICU Treatment

Tracking Atrial Fibrillation After Intensive Care Admission

Observational University of Oxford · NCT05229211

This study is testing if a special chest patch can help monitor patients for new atrial fibrillation after they leave the ICU to see how often it comes back.

What this trial studies

This study aims to assess the feasibility of screening patients for new onset atrial fibrillation (AF) after their admission to an intensive care unit (ICU). Patients without a prior history of AF who develop this condition during their ICU stay will be continuously monitored for 14 days post-discharge using a chest patch for cardiac rhythm monitoring. Follow-up assessments will occur at three months post-discharge to evaluate the recurrence of AF. Data on medical history and post-hospitalization complications will also be collected to understand the long-term outcomes of these patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 16 years or older who have been admitted to the ICU for more than 24 hours and have developed new onset atrial fibrillation.

Not a fit: Patients with a prior history of atrial fibrillation or those unable to undergo cardiac monitoring will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the management and monitoring of patients at risk for atrial fibrillation after critical illness.

How similar studies have performed: While studies on atrial fibrillation monitoring exist, this specific approach of post-ICU monitoring for new onset AF is novel and has not been extensively tested.
