Multiple Choice

The axis of the heart as a whole is called the _____ _____ _____, which shows the overall direction of flow within the heart.

Explanation:
The main idea is that the heart’s overall electrical direction is described by the average direction of its ventricles’ activation. The QRS complex represents ventricular depolarization, which is the largest and most consistent vector in the heartbeat. Therefore the mean QRS axis serves as the best reflection of the heart’s overall flow direction on the ECG. The P wave axis would indicate atrial depolarization and isn’t the global axis; a general “electrical axis” term is too broad, and “vector axis” isn’t the standard description used clinically.
