Abstract: Heart failure (HF) is the main cause of mortality in North America and it has a significant social and economic cost. As recent studies indicate, there is a relationship between heart rate at discharge time and mortality and hospitalization in patients with HF. Hence, heart rate could be monitored as another clinical indicator in HF patients transitioning from hospital to ambulatory care. Current heart rate monitors mostly have one of the following issues: 1) they are used in clinical setting and lack the user-friendly interface for a continuous monitoring system, 2) or designed to be used as wellness devices and not validated against clinical gold standard systems. This work describes the design, development and evaluation of a wearable heart rate and ECG monitoring system called BeatHR that allows patients to monitor heart rate in an ambulatory setting. BeatHR is able to capture and stream ECG signal and heart rate values in real-time via using a chest patch and a smartphone application. It also allows the user and their clinician to review the heart rate values above a pre-defined threshold, which could be defined based on the user's condition. The BeatHR system was compared to a clinically accepted gold standard, Holter monitor, and was found to generate comparable result overall with Intra-class correlation coefficients as high as 0.954.
