Area of Science:

  • Cardiology
  • Medical Diagnostics
  • Computational Biology

Background:

  • Exercise electrocardiogram (ECG) tests are crucial for diagnosing myocardial ischemia.
  • ST-segment depression/heart rate (ST/HR) analysis improves diagnostic accuracy.
  • New continuous diagnostic variables (ST/HR slope, ST/HR index, ST/HR hysteresis) have emerged.

Purpose of the Study:

  • To present a computer program for calculating and visualizing ST/HR diagnostic variables.
  • To provide a tool for clinical and medical researchers evaluating ST/HR analysis.
  • To facilitate the development of ST/HR analysis in exercise ECG diagnosis.

Main Methods:

  • Development of a computer program to process ST/HR data.
  • Calculation of ST/HR slope, ST/HR index, and ST/HR hysteresis.
