Using smartwatches to detect arrhythmias during heart palpitations

Diagnostic Accuracy in the Detection of Arrhythmias of Patient Recorded ECGs With Smart WATCH TIMEly Performed During Palpitations

University Hospital of Ferrara · NCT06482320

This study is testing if smartwatches can help people with heart palpitations accurately detect different types of irregular heartbeats, especially atrial fibrillation.

What this trial studies

This observational study aims to evaluate the diagnostic accuracy of single-lead ECGs recorded by patients using smartwatches during episodes of heart palpitations. Approximately 100 patients over the age of 22 will be enrolled, all of whom must own a compatible smartwatch. The study will collect clinical and electrocardiographic data from these patients as they report to outpatient clinics. The goal is to determine how effectively these self-recorded ECGs can identify various types of arrhythmias, particularly atrial fibrillation.

Who should consider this trial

Good fit: Ideal candidates are patients aged 22 and older who experience heart palpitations and own a smartwatch capable of recording ECGs.

Not a fit: Patients under 22 years of age or those with implanted cardiac devices such as ICDs or pacemakers will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a cost-effective and accessible method for diagnosing arrhythmias in patients experiencing palpitations.

How similar studies have performed: While the use of smartwatches for ECG recording is gaining popularity, this specific approach to diagnosing arrhythmias through patient-recorded data is relatively novel.
