As a domain expert in cardiology, I can tell you that the J point on an ECG (electrocardiogram) is a critical point that marks the end of the depolarization phase and the beginning of the repolarization phase of the cardiac cycle. It is the point at which the QRS complex ends and the ST segment begins. The J point is significant because any deviation from the baseline at this point can be indicative of various cardiac conditions, including ischemia or infarction.

On the ECG, the repolarization phase starts at the junction, or j point, and continues until the T wave. The ST segment is normally at or near the baseline. Minor STT changes are not necessarily associated with cardiac ischemia[1]. The T wave is usually concordant with the QRS complex.
