Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Occlusion of this artery results in high-degree heart blocks on the EKG.
A
LAD
B
Sinoatrial Artery
C
RCA
D
Atrioventricular Artery
Explanation: 

Detailed explanation-1: -CHB is most commonly associated with an occlusion of the right coronary artery (RCA) [3]. The mortality rate of MI is higher if complete heart block is present [1-3]. Thus, prompt recognition of CHB in myocardial infarctions is essential to prevent further deterioration.

Detailed explanation-2: -Patients on multiple nodal agents (eg, beta-blockers and calcium channel blockers) are at an increased risk for the development of third-degree atrioventricular (AV) block (complete heart block); the more nodal blockade that occurs, the higher the chance of developing complete heart block.

Detailed explanation-3: -Atrioventricular block is a heart rhythm disorder that causes the heart to beat more slowly than it should. It’s caused by communication problems within the heart’s electrical conduction system. For some people, the condition doesn’t cause symptoms; for others, it may be life-threatening.
