Overview
Brief Summary
Atrial fibrillation (AF) is a serious public health problem because of its increasing incidence and prevalence in the aging population. ECG is the most commonly used gold standard for clinical diagnosis of arrhythmias, but conventional ECG examinations are not adequate for long-term ECG follow-up measurements in patients with AF.
In this study, the AF patients will wear an watch and ECG patch to continuously monitor ECG and PPG. The software uses an integrated diagnostic mechanism of "AF burden + AF segments" to efficiently analyze ECG and PPG data, which can quickly and accurately identify the occurrence of AF and analyze AF burden in real-time, facilitating physicians' diagnosis and treatment and efficacy assessment.
Detailed Description
PPG-AF study is a Cohort randomized observational study.The trial will include patients with AF who meet the study requirements from Beijing Anzhen Hospital within 2 months. Each participant will wear an watch and ECG monitor after admission to hospital until Radiofrequency ablation for AF, and after AF ablation until discharge. And more than 18 hours in each period. 1. Primary endpoint. The ECG and PPG data are automatically analyzed by the AF analysis software. The results are compared with expert-annotated gold standard results to verify the sensitivity and specificity. 2. Secondary endpoints. The AF burden calculated from PPG data is compared with that from ECG monitoring, to verify the feasibility of daily monitoring of AF burden using PPG analysis.
