What is the term for the point where the QRS complex meets the ST segment?

• A. Q point
• B. S point
• C. J point
• D. T point

Answer: (C)

The term for the point where the QRS complex meets the ST segment is known as the J point. This point is clinically significant as it marks the transition from ventricular depolarization, represented by the QRS complex, to the beginning of repolarization, signaled by the ST segment. The J point can be an important indicator in the assessment of various cardiac conditions. Notably, changes at the J point can be indicative of ischemic events or other types of myocardial injury. Understanding the significance of the J point is crucial for interpreting ECGs accurately, as it helps in recognizing abnormalities in cardiac repolarization processes.
