Why are the ordered in EKG?

The waves in an EKG (electrocardiogram) are ordered to reflect the sequence of electrical events in the heart. The P wave represents atrial depolarization, followed by the QRS complex, which signifies ventricular depolarization, and finally the T wave, indicating ventricular repolarization. This ordered representation allows healthcare providers to assess the heart's rhythm, electrical activity, and overall health. Abnormalities in this sequence can indicate various cardiac conditions.
