Area of Science:

  • Cardiology
  • Biomedical Engineering
  • Medical Diagnostics

Background:

  • A significant subset of patients with coronary artery disease experience ischemic episodes without anginal pain.
  • Detecting these silent ischemic events is crucial for effective patient management.
  • Existing Holter analysis methods struggle with artifact sensitivity and differentiating ischemic from non-ischemic ST-segment changes.

Purpose of the Study:

  • To introduce a novel ST-segment analysis algorithm for computer-based Holter monitoring.
  • To improve the accuracy and reliability of detecting silent ischemic episodes in patients with coronary artery disease.

Main Methods:

  • Development and integration of a new ST-segment analysis algorithm into an existing Holter analysis system.
  • The algorithm is designed to be highly artifact-resistant.
  • Emphasis on maintaining high processing speed without compromising accuracy.

Main Results:

  • The new algorithm demonstrates high accuracy in detecting ischemic episodes.
  • The system exhibits significant resistance to artifacts, a common issue in Holter analysis.
  • Processing speed is minimally impacted, ensuring efficient analysis.

Conclusions:

  • The developed ST-segment analysis algorithm offers a more reliable method for detecting silent myocardial ischemia via Holter monitoring.
  • This advancement can lead to better identification and management of coronary artery disease in patients experiencing silent ischemic episodes.
