Mobile device based HRV analysis system

Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat interval. HRV signal can be collect from Mobile Wireless Electrocardiogram (EKG) devices by measures small electrical signals from the patient's chest. Using these signals, doctors and other medical staff can monitor the patient's well-being and predict future problems. In this design, we has built a prototype for the mobile wireless EKG unit as well as chosen software for the wireless transmission and base station. The mobile unit can be worn by the patient, and can measure heart rhythm data, digitize it, and transfer it wirelessly back to the base station. At the base station the software can store the data and allow doctor view and analysis the HRV signals.
