Summary
This study describes a novel heart rate biofeedback system for monitoring and controlling heart rate. The system uses a minicomputer and various input/output devices for real-time feedback and automatic level adjustment.
Area of Science:
- Biomedical Engineering
- Physiological Monitoring
- Biofeedback Systems
Background:
- Heart rate variability is a key indicator of cardiovascular health.
- Biofeedback systems offer a non-invasive method for physiological self-regulation.
- Accurate and real-time heart rate monitoring is crucial for effective biofeedback.
Purpose of the Study:
- To describe a newly developed heart rate biofeedback system.
- To detail the components and functionality of the system.
- To introduce a method for automatic adjustment of feedback criteria.
Main Methods:
- Utilized a JPR 12 minicomputer (12-bit, 4K memory).
- Integrated input devices: EEG R-wave triggered circuit and photoelectric ear lobe pulse detector.
- Implemented output devices: feedback indicator, teletype, and paper tape punch.
Main Results:
- The system measures actual heart rate and compares it to adjustable levels.
- Automatic shifting of comparison levels occurs when a preset criterion is met.
- Control sessions utilized shuffled data from previous experimental sessions for feedback.
Conclusions:
- The described system provides a functional platform for heart rate biofeedback.
- The automatic adjustment mechanism enhances the adaptability of the biofeedback protocol.
- This system has potential applications in cardiovascular research and training.
