Stress Test System (Model DG7000-S)

It is a complete digital system for high-performance stress tests, capable of analyzing a large number of parameters in real time, including 12-lead ECG, ST and QT intervals. Stress test software can be used for full control of many commercial treadmills and ergometers. Software module will continuously save the entire ECG with HRV evaluation and the PC will automatically control the treadmill.
