Keywords:heart rate monitor fundamentals? ECG devices? implementation Freescale products?

This application note demonstrates fundamental implementations of the cost-effective heart rate monitor (HRM) and electrocardiograph (ECG or EKG) devices using Freescale products. The heart rate monitor is implemented on a low-cost MC9RS08KA2 ultra low-end 8bit microcontroller using an analog comparator module (ACMP) and standard IO pins. The electrocardiograph is implemented on the MC9S08JM60 USB device 8bit microcontroller using an ADC and USB connectivity to send data to a PC.

This document is intended to be used by biomedical engineers, medical equipment development engineers or any person related with medicine and interested in understanding the operation of HRMs and ECGs. However, it is necessary to know the fundamentals of electronic analog and digital circuits.
