How is a right ventricular myocardial infarction typically confirmed?

Explanation:
Right ventricular infarction is confirmed most reliably by detecting injury to the right ventricle with ECG leads placed on the right chest (such as V4R and other right-sided leads). These right-sided leads reveal ST-segment elevations that indicate involvement of the RV, which the standard left-sided 12-lead ECG can miss. Hemodynamic measurements like central venous pressure or wedge pressure reflect preload and left-heart pressures, respectively, and while they may be altered in RV infarction, they do not provide a definitive diagnosis. A normal CVP wouldn’t rule out RV infarct, and LVEDP (wedge pressure) mainly informs left-sided function, not confirmation of RV injury.
