The Edan Vector ECG function is an advanced clinical diagnostic software module designed to enhance the analytical capabilities of the Edan Holter Analysis System. This specialized feature converts standard multi-channel ECG data into a three-dimensional vectorcardiogram (VCG), allowing clinicians to analyze the electrical activity of the heart from multiple spatial planes. By tracking the loop trajectories of the P, QRS, and T waves, this algorithm provides highly precise data for diagnosing chamber hypertrophy, myocardial infarctions, and complex conduction abnormalities.
