A Wireless Single Lead ECG Module for Cloud-Computing Based Postoperative Monitoring of Cardiac Surgical Patients

Abstract

Optimal postoperative care is critical after cardiac surgery to prevent hospital readmission. Miniaturized vital sign monitoring systems outside of critical care settings provide early detection of vital sign deterioration in high risk patients. This paper presents a wireless body sensor system to capture electrocardiogram (ECG) data which is transmitted to computer via a Bluetooth interface. A custom-designed programmable interface is developed for signal conditioning and real-time observation of heart rate variability, and arrhythmia detection on a cloud based server.
