J point

from DocCheck Flexikon, share & find medical know how

In ECG, the J point (also: junction point) marks the intersection of QRS complex and ST segment. It represents the transition from phase I to phase II of the action potential.

The J point may deviate from the baseline in pathologic conditions: I is often depressed in the case of cardiac ischemia, and in ergometry if coronary artery disease is present. Elevations of the J point are seen e.g. in cases of Brugada syndrome.
