As a medical professional with expertise in cardiology, I can explain that the P wave is a critical component of the electrocardiogram (EKG or ECG). It signifies the depolarization of the atria, which is the initial phase of the heart's electrical conduction system that leads to atrial contraction. The P wave appears before the QRS complex, which is responsible for the ventricular depolarization. A normal P wave has an amplitude ranging from 0.05 to 0.25 millivolts (mV), and it looks like a small bump that rises above the baseline of the EKG tracing.

The P wave represents atrial depolarization. In a normal EKG, the P-wave precedes the QRS complex. It looks like a small bump upwards from the baseline. The amplitude is normally 0.05 to 0.25mV (0.5 to 2.5 small boxes).
