First of all, we would like to appreaciate your deep interest in our case report. Fortunately, we have a previous electrocardiogram (ECG) of the patient before the symptom onset (Fig. 1). And we did check the serial ECGs during the admission. At initial admission, there were no prominent ST and voltage changes in precordial leads (Fig. 2). Follow-up ECG taken after 3 hours from the first ECG sh...

BACKGROUND T-wave inversion in right precordial leads V(1) to V(3) is a relatively common finding in a 12-lead ECG of children and adolescents and is infrequently found also in healthy adults. However, this ECG pattern can also be the first presentation of arrhythmogenic right ventricular cardiomyopathy. The prevalence and prognostic significance of T-wave inversions in the middle-aged general ...

This is a clinicopathologic study of 2 patients who electrocardiographically presented so called "masquerading" bundle-branch block. The conduction systems and the entire hearts of these patients were studied pathologically by methods especially devised by Lev for electro-cardiographic correlation. This report is part of a long-term project attempting to ascertain the anatomic substrate of elec...

BACKGROUND The response of the ST-segment in the right precordial leads to Na+ channel blockers in patients without structural heart disease and a typical Brugada-type ECG has not been fully elucidated. METHODS AND RESULTS A pilsicainide challenge test was performed in 161 patients and according to recently established ECG criteria and an organized computer algorithm, the ST morphology was cl...

OBJECTIVES The aim of this study was to evaluate whether the occurrence of the Brugada Syndrome typical electrocardiogram (ECG) pattern (i.e., right bundle branch block, coved-type ST-segment elevation, and T-wave inversion in the right precordial leads) is characterized by a concomitant lengthening of QT intervals in the right precordial leads. BACKGROUND It has been suggested that the typic...

OBJECTIVE To determine the diagnostic and prognostic impact of abnormal Q waves in comparison to or in combination with ST segment abnormalities in the right precordial and inferior leads as indicators of right ventricular infarction during the acute phase of inferior myocardial infarction. DESIGN Prospective study of a consecutive series of 200 patients with acute inferior myocardial infarct...

BACKGROUND It is well known that cardiologists empirically judge the culprit lesion of acute ST-segment elevation myocardial infarction (STEMI) according to the corresponding electrocardiographic leads. However, In addition to the obstruction of left anterior descending (LAD) coronary artery, rare cases with the occlusion of proximal right coronary artery (RCA) and/or isolated right ventricular...
