ERS is a newly designed piece of PC software offering superior training and monitoring control in order to assist therapists and physicians with their daily routines. The ERS is capable of conducting cardiovascular training combined with simultaneous monitoring of the ECG with up to 16 patients at a time. Using predefined protocols, the entire training session for each patient can be controlled by the ERS software. It is simultaneously able to document all of the relevant data, such as the heart rate, ECG and training data, which aids more intense supervision of the patients as the therapist has been relieved of having to perform the routine tasks.
