EXERCISE MONITORING SYSTEM

摘要

Apparatus and method for monitoring exercise activity and exercise responses of a user/patient. The monitoring apparatus and method forms the basis of a physical fitness system or a patient rehabilitation system for rehabilitating cardiac, orthopedic or other patients that require physiological monitoring during a therapy session. The system includes a patient station which in the case of cardiac rehabilitation includes an ECG monitor and a transmitting unit for transmitting ECG data and patient speech signals over a voice grade phone line. A base unit, located at a remote location, receives a composite analog signal containing the ECG data and voice signal and includes signal processing devices for separating the signal and for continuously storing the ECG data on a mass storage device for the entire therapy session. At the conclusion of the therapy session, selected portions of the stowed ECG data can be transferred to a removable storage medium such as a floppy disk. The base station includes means for transmitting commands in the form of DTMF tones to the patient station to initiate the therapy session and in a more preferred embodiment, to control the work load of an exercise device being used by the patient. The remote patient is preferably connected to the patient transmitting unit by a fiber optic link. Local patients are connected to the base unit by a RF link. The ECG data is transmitted in a frequency band of substantially 2170 Hz to 2370 Hz using frequency modulation on a carrier of substantially 2270 Hz. The system includes notch and band pass filters for removing the selected frequency band from the voice signal.
