Trial summary

The project focuses on the evaluation of a novel, contactless monitoring technology to measure the blood pulsatile signal based on the video recording of an individual's face. The variability of the pulse rate is computed to identify the presence of atrial fibrillation (AF). Read more about this study

About this study

Official title: Home-based Videoplethysmographic Detection of Atrial Fibrillation

The project focuses on the evaluation of a novel, contactless monitoring technology to measure the blood pulsatile signal based on the video recording of an individual's face. The variability of the pulse rate is computed to identify the presence of atrial fibrillation (AF). We propose to enroll 315 patients with symptomatic AF, paroxysmal or persistent, who go through successful radiofrequency ablation or electrical cardioversion. A computer tablet will be used by the subjects at home during 14 days after their procedure to read emails, browse the internet and watch videos. Facial video recordings will be automatically acquired during these daily activities by the tablet device. The subject will be wearing an ECG patch during the follow-up period. The one-lead continuous ECG will be used as a reference to verify the presence of AF rhythm during facial video recordings. The primary aim of the study is to demonstrate the validity and robustness of the video-based technology to detect the presence of AF when facial videos are acquired by the patients at home.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Facial video of detection of cardiac diseaseDiagnostic test

    This project proposes to evaluate a non-contact video recording technology to detect the presence of AF. The technology extracts a pulsatile signal by measuring the subtle variations in skin color of a patient's face (flushing) due to the variations of blood volume underneath the skin. The technology uses a standard web camera. This technique is videoplethysmography (VPG).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Area Under the Receiver Operating Characteristic Curve (AUC) for the Detection of Atrial Fibrillation

    The outcome measure is the AUC of the curve obtained from the ROC analysis. The curve is a combination of specificity and sensitivity of detecting atrial fibrillation. The range of the curve is 0.5-1.0 where 0.5 would be random detection of atrial fibrillation and 1.0 would be perfect performance.

    Measured: 2 weeks
