Abstract
A heart rate bio-feedback system having a heart rate display means by which a patient recognizes his heart rate data that are obtained from the pulse or the heart beat signal detected from the patient, characterized in that the heart rate display means comprises a display means for displaying the momentary heart beat and a digital display circuit for displaying the integrated number of heart beats at a longer time interval.
Claims4
A heart rate bio-feedback system comprising:
- detector means for detecting the pulse rate of a subject and converting it into a pulse rate signal;
- integrating circuit means for integrating said pulse rate signal over a set time interval;
- timing generator means for setting said time interval;
- display means comprising a display indicator means coupled to said detector means for displaying the momentary pulses of said pulse rate signal, and a digital display means coupled to said integrating circuit means for displaying the integrated pulse rate signal for said set time interval;
- variable controlled oscillator means for providing indicating signals independent of the pulse rate at a selective predetermined rate for use as an external stimulus for intensifying the biofeedback process, and
- an external stimulus visual display means for displaying said indicating signal simultaneously with the display of said momentary pulses.
