Question

Your chest pain patient has elevation in leads V5 and V6 on the 12 lead ECG. What coronary artery is most likely​ occluded?

A. Left circumflex artery
B. Right coronary artery
C. Left anterior descending artery
D. Marginal artery

Answer 1

The occlusion in leads V5 and V6 on the 12 lead ECG suggests an occlusion in the left anterior descending artery (LAD).

Step-by-step explanation:

The elevation in leads V5 and V6 on the 12 lead ECG indicates an occlusion in the left anterior descending artery (LAD). The LAD is the larger anterior interventricular artery that arises from the left coronary artery. It follows the anterior interventricular sulcus around the pulmonary trunk and supplies blood to the anterior portion of the heart, including leads V5 and V6.
