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.

Catheter ablation has emerged as an important treatment option for patients with symptomatic atrial fibrillation (AF). Pulmonary vein antral isolation (PVI) is now considered the cornerstone technique of AF ablation and has shown promise in treating paroxysmal atrial fibrillation (PAF). However, there is no unique strategy for ablation of persistent AF (PeAF), whether PVI alone is sufficient to prevent patients from recurrence remains controversial. The PROMPT-AF study is a prospective, multicenter, randomized trial involving a blinded assessment of outcomes, which is designed to compare arrhythmia-free survival between PVI and an ablation strategy termed upgraded '2C3L' for ablation of PeAF.
