A single normal cardiac cycle on an electrocardiogram (ECG) consists of several distinct waves and intervals, reflecting the electrical depolarization and repolarization of the atria and ventricles.
This article provides an in-depth exploration of the standard ECG complex, breaking down the physiology, the graphical representation, and the clinical significance of each component. standard ecg complex
A "normal" P wave suggests that the impulse is coming from the SA node and that the atria are conducting electricity properly. A single normal cardiac cycle on an electrocardiogram
