ECG system with heart rate variability application

An electrocardiogram (ECG) is a standards test for cardiac testing. The ECG in commercial system is too expensive and most of them using thermal printing. On this research, we developed the ECG system that display and record in digital form. The interface of this system designs on personal computer. The ECG circuit box is connected to computer by USB port. The ECG program is graphic user interface (GUI) that can changes sampling rate, detects heart rate and finds heart rate variability. This system can transferable via local area networks (LANs) or the internet to another remote site in the telemedicine application.
