Why the study?
Does the presence of ST-segment elevation in lead V4R predict major complications and in-hospital mortality in patients with acute inferior myocardial infarctions?
Does the presence of ST-segment elevation in lead V4R predict major complications and in-hospital mortality in patients with acute inferior myocardial infarctions?
Routine electrocardiographic assessment of lead V4R is crucial in acute inferior myocardial infarction as ST-segment elevation strongly predicts major complications and in-hospital mortality.
May support V4R assessment for risk stratification in inferior MI; extends observational data but leaves open therapeutic implications.
Right ventricular involvement during acute inferior myocardial infarction can be accurately diagnosed by the presence of ST-segment elevation in lead V4R, a finding that is a strong, independent predictor of major complications and in-hospital mortality. Electrocardiographic assessment of right ventricular infarction should be routinely performed in all patients with acute inferior myocardial infarctions.
