148 – Automated ECG Analysis


ECG Analysis

An electrocardiogram (ECG) is a graphical recording of the changes occurring in the electrical potentials between different sites on the skin as a result of cardiac activity. The electrical activity of the heart is a sequence of depolarizations and repolarizations. Depolarization occurs when the cardiac cells, which are electrically polarized, lose their internal negativity. The spread of depolarization travels from cell to cell, producing a wave of depolarization across the entire heart. This wave represents a flow of electricity that can be detected by electrodes placed on the surface of the body. Once depolarization is complete, the cardiac cells are restored to their resting potential, a process called repolarization.

This flow of energy takes on the form of the ECG wave and is characterized by an initial P wave, followed by the QRS complex, and then the T wave. The P wave is associated with depolarization of the atria, the QRS complex is associated with depolarization of the ventricles, and the T wave with repolarization of the ventricles.

This application note is designed to assist with the advanced analysis of ECG data, specifically P, Q, R, S and T Wave analysis. This Application Note describes how to set up the AcqKnowledge software to find R time, R height, Rate, Inter-Beat Interval, S height, P height, Q height, and T height and how to place your measurements into the journal.
