This study introduces a practical, portable electrocardiogram (ECG) mapping system, simplifying body surface potential mapping (BSPM) by using a notebook computer and a scalable 134- to 256-channel acquisition unit.

Area of Science:

  • Biomedical Engineering
  • Medical Imaging
  • Cardiology

Background:

  • Body surface potential mapping (BSPM) requires complex multi-channel systems, hindering widespread clinical use.
  • Existing ECG mapping technologies often lack portability and scalability.

Purpose of the Study:

  • To introduce a practical and portable electrocardiogram (ECG) mapping system.
  • To overcome the limitations of complex multi-channel measuring systems in BSPM.

Main Methods:

  • Developed a portable system using a notebook computer and a data acquisition box with a fast IEEE 1284 parallel interface.
  • Designed a scalable ECG amplifying unit, expandable from 134 to 256 channels.
  • Created application software for real-time ECG monitoring, signal processing, and body surface potential map generation.
