Patients who are randomised to the 30-day smartphone ECG monitoring will be contacted within one month from randomisation. Patients will be taught on how to use the smartphone ECG monitoring. Patients are required to monitor their ECG 3 times a day for 30 days. Patients will be contacted during the monitoring period to assess for compliance and to ensure that the recording is done correctly.
