This study introduces a novel method for recording vectorcardiographic (VCG) loops using a microdot thermal printer and minimal memory. This technique extends standard electrocardiogram (ECG) capabilities for enhanced cardiac diagnostics.

Area of Science:

  • Biomedical Engineering
  • Cardiology
  • Medical Instrumentation

Background:

  • Vectorcardiography (VCG) traditionally requires significant data storage.
  • Conventional 12-lead electrocardiogram (ECG) systems are widely adopted.
  • Biomedical signal recording technologies are advancing.

Purpose of the Study:

  • To develop a principle for recording VCG loops using a microdot thermal printer with a small memory footprint.
  • To integrate VCG recording as an extension of standard ECG.
  • To demonstrate the feasibility of the developed principle in ECG instruments.

Main Methods:

  • Deriving orthogonal electrocardiogram signals from a conventional 12-lead system.
  • Applying a microdot thermal printer for biomedical signal recoding.
