Right ventricular infarction: diagnostic accuracy of electrocardiographic right chest leads V3R to V7R investigated prospectively in 43 consecutive fatal cases from a coronary care unit.
Key result
ST elevation ≥ 1 mm in right chest leads V6R and V7R reliably diagnosed inferior/posterior right ventricular infarction, with specificity and positive predictive value reaching 100%.
Why the study?
Does ST elevation in right chest leads V3R to V7R accurately diagnose right ventricular infarction compared to necropsy findings?
Population
43 consecutive patients who died in a coronary care unit
Comparison
Electrocardiographic right chest leads V3R to V7R vs Necropsy findings (gold standard)

Does ST elevation in right chest leads V3R to V7R accurately diagnose right ventricular infarction compared to necropsy findings?
P
Population
43 consecutive fatal cases from a coronary care unit evaluated prospectively to determine the diagnostic accuracy of right chest leads for right ventricular infarction.
E
Exposure
Electrocardiographic right chest leads V3R to V7R (ST elevation ≥ 1 mm)
C

Diagnostic accuracy (sensitivity, specificity, and positive predictive value) for right ventricular infarctionsurrogate
ST elevation in right chest leads V6R and V7R provides highly specific and reliable diagnosis of right ventricular infarction in patients with inferior/posterior myocardial infarction.
Cite This Study
Andersen et al. (1989) conducted an observational in Right ventricular infarction (n=43). Electrocardiographic right chest leads V3R to V7R vs. Necropsy findings was evaluated on Diagnostic accuracy of ST elevation ≥ 1 mm for right ventricular infarction. ST elevation ≥ 1 mm in right chest leads V6R and V7R reliably diagnosed inferior/posterior right ventricular infarction, with specificity and positive predictive value reaching 100%.
