Electrocardiogram is a powerful tool for differentiating acute ST-segment elevation myocardial infarction (STEMI) and pericarditis. However, an unusual ECG presentation of the simultaneous occurrence of the two conditions has not been reported previously. In this article, we report a case of ECG evolution of acute anterior STEMI following pericarditis with pericardial effusion (PE) and find that QRS complex widening in ECG lead with maximal ST-segment elevation is also applicable for identifying STEMI even in patients with prior pericarditis. Undoubtedly, our case can help prevent emergency physicians from making incorrect diagnoses and administering inappropriate treatments.

UI MeSH Term Description Entries
D010493 Pericarditis Inflammation of the PERICARDIUM from various origins, such as infection, neoplasm, autoimmune process, injuries, or drug-induced. Pericarditis usually leads to PERICARDIAL EFFUSION, or CONSTRICTIVE PERICARDITIS. Pleuropericarditis
D004562 Electrocardiography Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY. 12-Lead ECG,12-Lead EKG,12-Lead Electrocardiography,Cardiography,ECG,EKG,Electrocardiogram,Electrocardiograph,12 Lead ECG,12 Lead EKG,12 Lead Electrocardiography,12-Lead ECGs,12-Lead EKGs,12-Lead Electrocardiographies,Cardiographies,ECG, 12-Lead,EKG, 12-Lead,Electrocardiograms,Electrocardiographies, 12-Lead,Electrocardiographs,Electrocardiography, 12-Lead
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000072657 ST Elevation Myocardial Infarction A clinical syndrome defined by MYOCARDIAL ISCHEMIA symptoms; persistent elevation in the ST segments of the ELECTROCARDIOGRAM; and release of BIOMARKERS of myocardial NECROSIS (e.g., elevated TROPONIN levels). ST segment elevation in the ECG is often used in determining the treatment protocol (see also NON-ST ELEVATION MYOCARDIAL INFARCTION). ST Elevated Myocardial Infarction,ST Segment Elevation Myocardial Infarction,STEMI
D001145 Arrhythmias, Cardiac Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in HEART RATE, disorders of electrical impulse generation, or impulse conduction. Arrhythmia,Arrythmia,Cardiac Arrhythmia,Cardiac Arrhythmias,Cardiac Dysrhythmia,Arrhythmia, Cardiac,Dysrhythmia, Cardiac
D056988 Anterior Wall Myocardial Infarction MYOCARDIAL INFARCTION in which the anterior wall of the heart is involved. Anterior wall myocardial infarction is often caused by occlusion of the left anterior descending coronary artery. It can be categorized as anteroseptal or anterolateral wall myocardial infarction. Acute Anterior Wall Myocardial Infarction,Anterolateral Myocardial Infarction,Anteroseptal Myocardial Infarction,Myocardial Infarction, Anterior Wall,Anterolateral Myocardial Infarctions,Anteroseptal Myocardial Infarctions,Infarction, Anterolateral Myocardial,Infarction, Anteroseptal Myocardial,Infarctions, Anterolateral Myocardial,Infarctions, Anteroseptal Myocardial,Myocardial Infarction, Anterolateral,Myocardial Infarction, Anteroseptal,Myocardial Infarctions, Anterolateral,Myocardial Infarctions, Anteroseptal
