It is most commonly associated with hypothermia. These changes will appear as a reciprocal, negative deflection in aVR and V1.</p> <p>The <strong><a href="https://litfl.com/j-point-ecg-library/">J point</a></strong> in the ECG is the point where the QRS complex joins the ST segment. It represents the approximate end of depolarization and the beginning of repolarization as determined by the surface ECG. There is an overlap of around 10ms.</p> https://ecgvn.com/en/posts/j-point/ Fri, 07 Apr 2023 00:00:00 +0000 https://ecgvn.com/en/posts/j-point/ <p><strong>The J point</strong></p> <p>The <strong>J point</strong> is the the junction between the termination of the QRS complex and the beginning of the ST segment.</p> <p>The <strong>J (junction) point</strong> in the ECG is the point where the QRS complex joins the ST segment. It represents the approximate end of depolarization and the beginning of repolarization as determined by the surface ECG. There is an overlap of around 10ms.</p> <p>The J point marks the end of the QRS complex, and is often situated above the baseline, particularly in healthy young males. The J point may deviate from the baseline in early repolarization, epicardial or endocardial ischaemia or injury, pericarditis, RBBB, LBBB, RVH, LVH or digitalis effect.</p>
