    Area of Science:

    • Medical imaging
    • Cardiology
    • Diagnostic tools

    Background:

    • Vectorcardiography (VCG) is a diagnostic method that represents the electrical activity of the heart in three dimensions.
    • Accurate quantification of the VCG loop area is crucial for assessing cardiac health.
    • Traditional methods for calculating VCG loop area can be time-consuming and prone to error.

    Purpose of the Study:

    • To introduce a novel, simple, and accurate method for calculating the VCG loop area.
    • To demonstrate the utility of a preprinted transparent plastic chart for VCG analysis.

    Main Methods:

    • A transparent plastic chart featuring a grid of equally sized small squares was utilized.
    • This chart was overlaid on VCG tracings to facilitate area calculation.
