Investigating excessive supraventricular activity and its link to atrial fibrillation

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to determine whether individuals with excessive supraventricular ectopic activity (ESVEA) detected through Holter monitoring should undergo prolonged screening with an Event loop recorder to identify undiagnosed atrial fibrillation or flutter. The study will compare ESVEA patients with a matched control group, assessing various biomarkers, echocardiographic data, and cardiovascular health over a period of 21 months. Participants will also complete questionnaires and have blood samples collected for further analysis of potential atrial fibrillation biomarkers.
