Final answer:
Complete heart block is associated with occlusion of the right coronary artery (RCA).
Step-by-step explanation:
The complete heart block is associated with occlusion of the right coronary artery (RCA).
The right coronary artery distributes blood to the right atrium, portions of both ventricles, and the heart conduction system. It gives rise to the posterior interventricular artery, also known as the posterior descending artery, which runs along the posterior portion of the interventricular sulcus.
If the right coronary artery becomes occluded, it can lead to decreased blood flow and insufficient oxygen delivered to the heart tissues, potentially resulting in myocardial infarction or heart attack.
