The P wave in the ECG represents atrial depolarization, which results in atrial contraction.
On an ECG machine, the measurement of the upper heart chamber (or the atria) is called the P wave. A device will record the electrical activity that occurs during the procedure, and will compare the results to the other chambers of the heart.
