Which condition is most likely found in patients with an anterior wall myocardial infarction presenting with syncope?

In the context of an anterior wall myocardial infarction (MI) presenting with syncope, ventricular tachycardia (VT) is a plausible and significant option because it represents a rapid heart rhythm originating from the ventricles, which can occur when there is ischemia or infarction of the myocardial tissue. Anterior MIs are particularly associated with coronary artery disease affecting the left anterior descending artery, which supplies a significant portion of the heart muscle and can lead to ventricular irritability and subsequent arrhythmias such as VT.

VT can result in decreased cardiac output, leading to syncope—loss of consciousness due to insufficient blood flow to the brain. The presence of syncope in the setting of an anterior wall MI can be attributed to this arrhythmia, as it may result in periods of ineffective contractions and, consequently, impaired perfusion.

While ventricular fibrillation is also a potential complication of an MI that can cause syncope, it is usually more acute and more likely to cause cardiac arrest immediately rather than presenting with syncope first. Atrioventricular block may also occur, particularly in the setting of ischemia affecting the conduction pathways, but syncope due to an AV block is often more gradual and characterized by bradycardia rather than
