Where is the U wave located in relation to the other waves?

Explanation:
The U wave appears after the T wave as a small deflection following the main ventricular repolarization. In the normal ECG sequence, you have P wave (atrial depolarization), the QRS complex (ventricular depolarization), and the T wave (ventricular repolarization). When present, the U wave comes after the T wave, not before the P wave, not during the QRS, and not between the P wave and the PR segment. Its exact origin is a bit debated, but its location is consistently after the T wave, which is why choosing “after the T wave” is correct.
