Measurement of R-R Intervals with a Microprocessor
- 발행 : 1985.12.01
초록
This article developes a cost-effective on-line measurement system of R - R intervals in ECG. The system is composed of a R peak detector, a timer and an Apple II computer (a 6502 microprocessor and memories). The system measures the R - R intervals in msec and stores them in a disk, for off-line analysis. A circuit diagram of the R peak detector and programs for controlling the microprocessor are presented.
