Use of Smartphone Application to Detect Atrial Fibrillation After Ablation Procedure

This is a non-randomised trial where each participant will undergo concurrent monitoring using Holter and FibriCheck application on their smartphones at specific time frame for specific duration (stated below). Patients with symptomatic atrial fibrillation (AF) undergoing AF ablation procedure will be asked to use FibriCheck application on their smartphones to measure their heart rhythm. The app is available through the App Store and the subscription code will be provided to the participants for free thoughout the study duration. Participants will be provided both a written and oral instructions on how to use the app. Instructions are also readily available online at https://pages.fibricheck.com/ifu/app/2.1.3/en/. To start measuring, participants will be instructed to be in the seated position with the arm resting on a table, placing their (index) finger on the camera of the smartphone for 60 seconds. Participants will be asked to measure twice daily for a period of 28-days at an interval of every 3-months post-ablation for the duration of the study (3-month, 6-month, 9-month and 12-month). They will also be asked to take additional measurements at any point during the 28-days period if they experience any symptom (e.g palpitation, light headed, fatigue, chest pain, etc). Participants' adherence to monitoring schedule will be assess by accessing app analytics. The monitoring duration will also be scheduled to coincide with standard post-ablation clinic follow up with concurrent 4-day Holter monitoring at 3-monthly intervals. The overall duration of this study is 12 months.
