This study developed a versatile electrocardiogram (ECG) simulator for calibrating and maintaining ECG equipment. The simulator accurately mimics in vivo heart signals with adjustable parameters for precise testing.

Area of Science:

  • Biomedical Engineering
  • Medical Device Development
  • Physiological Signal Simulation

Background:

  • Electrocardiographic (ECG) equipment requires regular testing and calibration.
  • Accurate simulation of ECG signals is crucial for reliable equipment maintenance.
  • Existing simulators may lack the flexibility to replicate in vivo signal variations.

Purpose of the Study:

  • To design and develop a novel ECG simulator.
  • To provide a tool for testing, calibration, and maintenance of electrocardiographic equipment.
  • To create a simulator capable of generating realistic Lead II ECG signals with adjustable parameters.

Main Methods:

  • Development of a signal generation module for Lead II ECG.
  • Implementation of user-adjustable controls for heart rate (30-200 bpm).

  • Inclusion of adjustable parameters for QRS complex amplitude (0.1-20 mV) and up-slope (10-50 ms).
  • Capability to modify P-wave (5-40%) and T-wave (10-80%) amplitudes relative to QRS.

    • Main Results:

    • The developed ECG simulator generates a Lead II signal with heart rate-dependent variations.
    • User-adjustable parameters include heart rate, QRS amplitude and up-slope, and P/T wave amplitudes.
    • The simulator offers precise control over signal parameters, mimicking physiological variability.

    Conclusions:

    • The designed ECG simulator effectively supports the testing, calibration, and maintenance of electrocardiographic equipment.
    • Its adjustable parameters allow for realistic simulation of in vivo ECG signal variations.
    • This tool enhances the reliability and accuracy of ECG diagnostic equipment.
