Abstract

An ECG R-R interval recording system has been developed for a heart rate variability monitor. The recording system, which employs a low power 8-bit single chip microcontroller (SMC) and a 512 KB EEPROM, is constructed on three ECG chest electrodes. The ECG from the electrodes is converted to an 8-bit serial digital format by a 8-bit A/D converter in the SMC. The SMC detects the R wave and calculates the R-R interval, which is stored by the EEPROM. The system is powered by a small 3 V lithium battery, which provides 100 hours of continuous operation. The 28.5 cc system weighs 28 grams.
