Summary

A novel method visualizes heart electrical activity on the body surface using animated 3D electrocardiogram (ECG) graphs. This technique allows clear observation of ventricular activation wave propagation in real-time.

Area of Science:

Biomedical Engineering
Cardiology
Medical Imaging

Background:

Understanding heart electrical activity is crucial for diagnosing cardiac conditions.
Current methods for visualizing cardiac potential distribution can be complex and time-consuming.

Purpose of the Study:

To develop an innovative method for displaying heart electrical potential distribution on the body surface.
To create a dynamic, animated visualization of cardiac activity.

Main Methods:

Electrocardiograms (ECGs) were recorded from multiple points on the precordial region.
A digital computer was used to generate 3D graphs of potential distribution.
A derived interpolation method provided smooth, rapid approximations for animation.

Main Results:

A real-time, animated 3D display of potential distribution on the body surface was successfully created.
The method allowed visualization of the wave front transmission during ventricular activation.
Smooth, approximated curves were generated efficiently.

Conclusions:

The developed method offers a clear and intuitive way to visualize cardiac electrical activity.
This animation technique aids in understanding the dynamics of ventricular activation.
The approach shows potential for improved cardiac diagnostics and research.
