Detecting heart rhythm issues using ear sensors

Hearables: Ear Electrocardiography (ECG) and Photoplethysmography (PPG) for Real-time Detection of Cardiac Arrhythmias

Observational Imperial College London · NCT06667258

This study is testing if sensors placed in and around the ears can effectively detect heart rhythm problems in patients who already have these issues, compared to traditional heart monitoring methods.

What this trial studies

This observational study aims to assess the feasibility of using Electrocardiogram (ECG) and Photoplethysmogram (PPG) sensors placed in and around the ears to detect cardiac arrhythmias in patients already diagnosed with these conditions. Researchers will compare the effectiveness of ear-based recordings with traditional single-lead ECG methods. Participants will include both arrhythmia patients and healthy controls, with data collected during their hospital visits. The study will utilize standard medical-grade sensors and electrodes to capture heart rhythm data.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with cardiac arrhythmias who can provide informed consent.

Not a fit: Patients with abnormal ear anatomy may not benefit from this study due to the nature of the sensors used.

Why it matters

Potential benefit: If successful, this approach could provide a non-invasive and convenient method for monitoring heart rhythms in patients.

How similar studies have performed: While the use of ear-based sensors for ECG/PPG is innovative, similar studies have not been widely reported, making this approach relatively novel.
