Here's an application note that tackles how to use the MED-EKG development board, which can be connected to the Freescale Tower System to obtain an electrocardiogram signal and measure heart rate.

The demo can be implemented in the TWR-K53 module, a member of the Kinetis K50 microcontroller family, or in the Flexis MM family's TWR-MCF51MM or TWR-S08MM128.

This demo uses the Freescale USB stack to send data to a PC, making it possible to monitor heart activity through a graphical user interface (GUI).

The Tower System and MED-EKG board allow the user to implement heart signal conditioning in three different modes:
? With the internal OPAMPs and TRIAMPs of the microcontrollers.
? With the external instrumentation amplifier and operational amplifiers featured in the MED-EKG board.
? With a mixture of both. The information in this application note is intended for developers of medical applications, for those in the medical field, such as biomedical engineers or doctors, or for people who want to know more about the operation of heart rate monitors and electrocardiograph devices.
