Area of Science:

  • Biomedical Engineering
  • Digital Health
  • Cardiology

Background:

  • Traditional methods for recording heart sounds and ECG are often analog.
  • Digital storage and transmission offer advantages in data management and accessibility.

Purpose of the Study:

  • To develop a digital system for recording, storing, and transmitting heart sounds and electrocardiograms (ECG).
  • To enable high-fidelity digital display and reproduction of cardiac auscultation data.

Main Methods:

  • Developed a system using object-oriented C++ on a Macintosh platform (System 7.0-7.5).
  • Data acquired via standard heart sound microphone and ECG amplifier.
  • Sampled at 2 kb/s, stored as 16-bit words for 10-30 second intervals.

Main Results:

  • Successfully implemented a digital recording and playback system for heart sounds and ECG.
  • The system allows for file storage and transmission of cardiac data.
  • Achieved high-fidelity reproduction of recorded sounds.

Conclusions:

  • The developed system provides a robust digital solution for cardiac auscultation and ECG recording.
  • This digital approach enhances data handling, sharing, and analysis capabilities in cardiology.
  • Facilitates improved accessibility and fidelity of cardiac sound and electrical data.
