ECG of the month. Hypotension, pulmonary edema, and an irregular cardiac rhythm in a 50-year-old woman. Sinus tachycardia, type I (Wenckebach) second degree atrioventricular block, acute inferoposterior myocardial infarct, and anterolateral myocardial infarct of indeterminate age (probably old).
A 50-year-old woman came to the emergency department because of chest discomfort and dyspnea. She was found to have hypotension, oliguria, and pulmonary edema, i.e., full-blown cardiogenic shock, an irregular rhythm, and no cardiac murmur. The electrocardiogram (ECG) was recorded one lead at a time, and a lead II rhythm strip was mounted above the standard 12 leads (Figure 1).
