Background:
Atrial fibrillation (AF) is the most common arrhythmia, significantly contributing to complications such as stroke, heart failure, dementia, and increased mortality. Catheter ablation is widely used for treatment, but recurrence rates range from 15-50% within 12 months post-procedure. Conventional intermittent ECG monitoring lacks sufficient sensitivity to detect asymptomatic AF recurrence effectively.
Objective:
To compare the recurrence rates of atrial tachyarrhythmias between a 1-day monitoring group and a 14-day monitoring group using MEMO Patch 2 after catheter ablation in AF patients. The study also evaluates the effectiveness and safety of early recurrence detection via remote monitoring.
Study Population:
Patients diagnosed with AF and treated with catheter ablation.
Intervention:
Participants will undergo three sessions of remote ECG monitoring using MEMO Patch 2 and MEMO Link (first session only), spanning approximately one year after catheter ablation.
Hypothesis:
Long-term monitoring with MEMO Patch 2 will be more effective than 1-day monitoring in detecting the recurrence of atrial tachyarrhythmias (including AF, atrial flutter, and atrial tachycardia) following catheter ablation.
