Data Collection: Patient demographics, medical history, CSARS predictors, results of physical examination and investigations, and patient disposition will be collected. The following device data will be obtained from the central monitoring station: quality of recordings, device failure (rhythm not captured during death or when symptomatic), false alarms due to artefacts, times of patient activation of cardiophone device due to symptoms, any rhythm abnormalities detected during the symptoms, and monitoring reports for patients in both arms. Patients will complete a questionnaire during the follow-up visit regarding any serious conditions suffered, their comfort and how secure they felt because of the cardiac monitoring.
