Mr.Henry has ST segment elevations in II,III,and AVF along with reciprocal ST depression in I,AVL,and V1-4.Right-sided EKG shows ST elevation in V3-4R.His blood pressure is quite low.Mr.Henry is normally hypertensive.This description is consistent with
A)Pericarditis.
B)Early repolarization.
C)Inferior MI complicated by a right ventricular infarction.
D)Extensive anterior MI complicated by cardiogenic shock.

Question

Quizplus · Accepted Answer

The ST segment elevations in II, III, and AVF with reciprocal ST depression in I, AVL, and V1-4 suggest an inferior myocardial infarction (MI). Additionally, the ST elevation in the right-sided leads (V3-4R) is indicative of a right ventricular MI, which can occur in up to 50% of inferior MIs. The low blood pressure and history of hypertension suggest cardiogenic shock, which can occur in severe MIs. Therefore, the most likely scenario is an inferior MI complicated by a right ventricular infarction.
