In the setting of an acute anterior-wall myocardial infarction (AWMI), which management step is commonly anticipated?

• A. Monitoring for AV block and potentially using a temporary pacemaker
• B. Immediate coronary bypass surgery
• C. Routine observation with no arrhythmia risk
• D. Administration of nitroglycerin only

Answer: (A)

The main idea is that an anterior-wall MI can disrupt the heart’s electrical conduction, so keeping a close eye on rhythm and being ready to pace is a common and important part of management. When the LAD is occluded and the anterior wall is damaged, the conduction system in the septum can be affected, leading to bradyarrhythmias or AV block. These blocks can be transient or progress to hemodynamic compromise, so continuous rhythm monitoring with the capability to provide a temporary pacemaker is often anticipated while definitive revascularization is performed (through PCI or thrombolysis). This is why monitoring for AV block and having pacing available fits as the expected step. Relying on nitroglycerin alone won’t address the blockage or prevent conduction problems, routine observation misses the arrhythmia risk, and immediate bypass surgery is not the typical first-line action in this setting, since prompt reperfusion and hemodynamic security come first.
