This study introduces a novel ST segment analysis method for faster electrocardiogram (ECG) interpretation. The system aids physicians in rapid ECG signal review for improved diagnostic accuracy.

Area of Science:

  • Biomedical Engineering
  • Medical Informatics

Context:

  • Electrocardiogram (ECG) interpretation is crucial for diagnosing cardiac conditions.
  • Efficient analysis of ECG signals is needed to reduce diagnostic time.
  • Current methods may require significant physician time for signal review.

Purpose:

  • To develop a new ST segment analysis scheme for rapid ECG signal browsing.
  • To assist physicians in achieving accurate diagnoses by simplifying ECG interpretation.
  • To provide a tool for visualizing ST segment deviations and trends.

Summary:

  • A novel ST segment analysis scheme is presented, incorporating median filtering for baseline wander, order statistic filtering for noise reduction, and wavelet analysis for QRS complex detection.
  • The system computes total deviations between user-defined ST segments and modified baselines, plotting the trend for physician review.
