What does the term 'wave' refer to in ECG terminology?

Explanation:
On an ECG, a wave is the visible deflection on the tracing that reflects a heart electrical event. Each wave pattern corresponds to a specific electrical activity: the P wave shows atrial depolarization, the QRS complex shows ventricular depolarization, and the T wave shows ventricular repolarization. It’s not about heart sounds, blood pressure, or breathing. So a wave in ECG terminology refers to the pattern on the tracing that represents a particular electrical activity of the heart.
