Summary
Isolated right ventricular infarction (RVI) can cause ST-segment elevation mimicking other heart conditions. Vector analysis of electrocardiograms (ECGs) aids in accurately diagnosing RVI, even with lead placement errors.
Area of Science:
- Cardiology
- Medical Diagnostics
Background:
- Isolated right ventricular infarction (RVI) is an increasingly recognized cause of precordial ST-segment elevation (STE).
- Accurate diagnosis is crucial for appropriate management and improved patient outcomes.
Observation:
- A patient presented with ST-segment elevation (STE) in precordial leads V1-V5 following right coronary artery stent angioplasty.
- Initial interpretation suggested anteroseptal myocardial infarction due to STE pattern.
- Technical error of switched leads V2 and V3 was identified upon review.
Findings:
- ECG analysis, accounting for lead switch, revealed STE in V2>V3, favoring RVI.
- Spatial ST vector analysis showed a +120° frontal plane vector, causing ST depression in lead I.
- This vector pattern is indicative of right ventricular epicardial injury, not anteroseptal infarction.
Implications:
- Electrocardiogram (ECG) vector analysis is a valuable tool for diagnosing RVI, complementing pattern recognition.
- Correcting for technical errors like lead misplacement is essential for accurate cardiac diagnosis.
- This case underscores the importance of detailed ECG interpretation in differentiating myocardial infarction subtypes.

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
01:30Acute Coronary Syndrome I: Introduction
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...
01:28Cardiac Catheterization I: Pre-Procedure Overview
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
