4. Motivation

5. Methodology  PDA + ECG Acquisition Module  ECG Monitor  ECG Monitor  Mobility  Communication capability  Personal health care

6. System Implementation  System implementation  Block diagram  Testing architecture  HW/SW Co-design  iPAQ Pocket PC  Software Languages

7. Block Diagram of the Pocket PC Based ECG Monitor Block Diagram of the Pocket PC Based ECG Monitor Pocket PC (running Flymedic ECG) RS232 ECG Amplifiers and Filters ECG Acquisition Controller Optical Isolation ECG Data Acquisition Module Electrodes

8. Architecture of the Tele-monitoring System

9. Hardware/Software  Hardware  iPAQ Pocket PC  Pre-amplifier and Filters  Power Circuit  ADC and CPU  Communication Interface  PCB layout  Prototype  Software  Development Tools

10. iPAQ Pocket PC  H3630  Microsoft Windows for Pocket PC  Color screen with 240x320 resolution  206 MHz StrongARM SA-1110 32 bits RISC processor  32 MB SDRAM ; 32 MB Flash ROM  One standard serial port  950 mAh Li Battery

11. Pre-amplifier

12. Filters  Bandwidth = 0.5-50Hz

13. Power Circuit

14. ADC and CPU  Sampling rate = 200Hz, 10-bit resolution

15. Communication Interface  Baud rate = 57600BPS

16. Developmental Tools  Pocket PC  Microsoft embedded Visual C++ 3.0  Server site  Borland C++ Builder 5.0

17. Results  Lead II ECG waveform real-time displayed on the Pocket PC’s screen and the ECG waveforms displayed on the local center in real time.

18. Discussion  Combined with a GSM and GPS module, the monitoring device can be converted into an emergency care system.  There would be a lot of use for this product in a hospital or other areas where constant health monitoring is needed.  Hardware/Software design for biomedical needs.

19. Conclusions  The prototype of the Pocket PC based ECG monitor has been developed and tested.  PDA or Pocket PC based monitoring devices offer more mobility and communication capability and flexibility over the traditional ones.  For long-term recording, the power consumption of Pocket PC would determine the recording time.  Personal health management can also be accomplished via a customized program.
