The Heart Sound Simulator (HSS), or "Xinyinqin," is a user-friendly diagnostic teaching aid. This computer-based tool enhances medical training by allowing students to practice identifying various heart sounds and rhythms interactively.

Area of Science:

  • Medical Education Technology
  • Cardiology Simulation
  • Diagnostic Training Tools

Background:

  • Traditional diagnostic training relies on limited resources.
  • There is a need for interactive and accessible tools for auscultation practice.
  • The Heart Sound Simulator (HSS), named 'Xinyinqin', offers a novel approach.

Purpose of the Study:

  • To introduce the functions and application of the Heart Sound Simulator (HSS) as a teaching aid in Diagnostics.
  • To demonstrate the HSS's capability in heart sound auscultation training and assessment.
  • To highlight the user-friendly interface and interactive features of the HSS.

Main Methods:

  • The HSS connects to an Apple microcomputer via GAME I/O, with sound generation controlled by a program.

  • The system features a heart auscultation training module for selecting and listening to specific heart sounds.
  • An assessment module randomly simulates heart sounds for student identification, providing immediate feedback and repetition for incorrect answers.

    • Main Results:

    • The HSS has been successfully used in teaching Diagnostics for three years.
    • The system allows for adjustable heart rates (slowed or normal) and interactive control (pause, resume, change content).
    • Students can practice identifying various heart sounds and rhythms through interactive computer-based modules.

    Conclusions:

    • The Heart Sound Simulator (HSS) is an effective and convenient teaching aid for diagnostic training.
    • Its interactive features and user-friendly design facilitate improved auscultation skills.
    • Future development aims to expand the library of simulated heart sounds and incorporate visual aids.
