This study uses Support Vector Machines (SVMs) to accurately classify premature ventricular contractions (PVCs) from ECG data. The method analyzes heart rate, morphology, and wavelet energy for reliable arrhythmia detection.

Area of Science:

  • Biomedical Engineering
  • Signal Processing
  • Machine Learning

Context:

  • Automated arrhythmia monitoring relies on accurate heart beat classification.
  • Support Vector Machines (SVMs) offer advanced pattern recognition capabilities.
  • Premature Ventricular Contractions (PVCs) are a common type of arrhythmia.

Purpose:

  • To describe the application of SVMs for identifying PVCs in single-lead surface electrocardiograms (ECGs).
  • To extract and analyze features including heart rate, morphology, and wavelet energy for classification.
  • To evaluate the performance of various SVM models on a standard arrhythmia database.

Summary:

  • This research details an SVM-based approach for PVC detection using ECG signals.
  • Key features such as heart rate variability, beat morphology, and wavelet energy were extracted.
