The J point denotes the junction of the QRS complex

What does J point elevation indicate?

The term J-point elevation represents a family of ECG findings. It has been described in several metabolic disorders most notably hypothermia (abnormally low body temperature). Subtle nuances in its pattern may point to other conditions, the most common of which is termed ‘early repolarization’.

When is J point elevated?

The J point of the ECG is at the end of the QRS complex and the beginning of the ST segment. J point elevation can be seen in early repolarization. At times, J point elevation can be ischemic, however, this is somewhat rare.
