What is the name of the point where the QRS complex meets the ST segment during an EKG?

The point where the QRS complex meets the ST segment during an EKG is known as the J point. This point is significant because it marks the transition from ventricular depolarization to repolarization. During this interval, the heart muscle has completed its contraction and is beginning to reset for the next heartbeat. The J point represents the end of the QRS complex and the start of the ST segment, which is critical for assessing various cardiac conditions, such as ischemia or myocardial infarction. Understanding the J point is essential for accurately interpreting an EKG and recognizing potential abnormalities in the heart's electrical activity.
