This term marks the boundary between the end of the QRS and the beginning of the ST segment.

Think about where ventricular depolarization ends and ventricular repolarization begins. The boundary between the end of the QRS complex and the start of the ST segment is called the J point. It marks the junction where the rapid depolarization finishes and the flat ST segment begins, which is why ST changes are assessed relative to the J point. The P wave is atrial depolarization and occurs before the QRS; the Q point and T point refer to other features that don’t define this boundary.
