Abstract

A simple, compact and low-cost device is presented. It is able to measure, store and transfer to a computer the beat-to-beat interval of the heart, using a POLAR chest belt and receiver. The conception of this device is based on a microcontroller 8051 associated with flash memory and a real time clock. The statistical error on this interval is below one millisecond. The device suits particularly well for studying the heart rate variability (HRV) at rest in athletes.
