Core Tip

Core Tip: It is rarely observed that right coronary artery occlusion causes ST-segment elevation only in precordial leads without inferior lead elevation. Electrocardiograms are often used by cardiologists to identify the infarct-related artery. This case emphasizes the importance for cardiologists to be conscious that occlusion of the nondominant right coronary artery can cause precordial ST-segment elevation. Recognizing this is helpful for discriminating the culprit artery for timely reperfusion therapy.
