Apparent ST elevation in right bundle branch block pseudo-mimicking myocardial infarction

Abstract

We report a case of right bundle branch block, in which the patient’s symptoms and the electrocardiogram findings mimicked those of acute coronary syndrome. In this case report, we stress the significance of apparent ST segment elevation in right bundle branch block. The differential diagnosis is important because right bundle branch block is often complicated with acute coronary syndrome. In addition, right bundle branch block with an ST segment elevation in the specific leads can be a predictor of sudden cardiac death. In such cases, close monitoring of the electrocardiogram findings and careful observation of the patient’s symptoms would be necessary.

Subepicardial burn injuries in bullfrog heart induce electrocardiogram changes mimicking inferior wall myocardial infarction

“…However, in inferior wall myocardial infarction, the typical ECG changes represented by an elevation of the ST segment cannot always be detected obviously, since the degree of such change is often subtle in ECG limb leads [ 21 ]. Besides, the presence of the ST segment elevation alone does not confirm the diagnosis of acute myocardial infarction, because it is also observed in other cardiac disorders, including early repolarization, acute pericarditis, right bundle-branch block and Takotsubo cardiomyopathy [ 7 , 12 ]. “Reciprocal” ST segment change refers to a ST segment depression in ECG leads opposite to those that detect the ST segment elevation [ 20 ], which is frequently observed in acute inferior or anterior myocardial infarction.…”
