    VECTAN II analyzes vectorcardiograms (VCG) in 3D, using a novel spatial vector length algorithm for improved waveform recognition. This digital program quantifies cardiac responses during stress tests and in astronaut health assessments.

    Area of Science:

    • Cardiovascular physiology
    • Biomedical engineering
    • Computational biology

    Background:

    • Traditional vectorcardiogram (VCG) analysis often uses scalar or planar representations.
    • Previous waveform recognition algorithms have limitations in accuracy and scope.
    • Assessing cardiac function during physiological stress requires precise quantitative methods.

    Purpose of the Study:

    • To introduce VECTAN II, a digital computer program for advanced spatial analysis of the vectorcardiogram.
    • To present a novel waveform recognition algorithm based on spatial vector length for enhanced VCG analysis.
    • To quantify the VCG response of normal subjects during controlled stress experiments.

    Main Methods:

    • Developed VECTAN II, a digital program employing a unique spatial vector length-based waveform recognition algorithm.

  • Analyzed the vectorcardiogram as a three-dimensional entity, moving beyond scalar or planar interpretations.
  • Monitored VCG complexes every five seconds during prolonged stress experiments to capture dynamic cardiac changes.

    • Main Results:

    • The VECTAN II program demonstrated superior performance compared to previous VCG analysis algorithms.
    • Successfully quantified cardiac responses in normal subjects under controlled stress conditions.
    • Provided valuable data from astronaut health examinations (Apollo missions, Skylab) for cardiovascular research.

    Conclusions:

    • VECTAN II offers a more comprehensive and accurate method for spatial vectorcardiogram analysis.
    • The program's 3D approach and novel algorithm enhance the understanding of cardiac dynamics.
    • VECTAN II has proven utility in both controlled laboratory settings and critical aerospace medical evaluations.
