Aim of this study was to investigate the diagnostic accuracy of the conventional electrocardiogram (ECG) algorithm [ST-segment elevation (STE) in lead III exceeding that in lead II combined with ST-segment depression in lead I or aVL] for identification of the infarct-related artery (IRA) in a large cohort of patients undergoing primary percutaneous coronary intervention (PCI) for inferior wall STE myocardial infarction (STEMI). ⋯ The conventional ECG algorithm showed a low sensitivity for the non-invasive diagnosis of RCA occlusion in an all-comer, inferior STEMI cohort undergoing primary PCI. Sensitivity was only sufficient in patients with extensive ST-segment deviation.

Case Reports
The complete array of electrocardiogram abnormalities secondary to myocardial contusion in a single case.
Myocardial contusion is a complication of blunt thoracic injuries. Transthoracic echocardiography and electrocardiography (ECG) monitoring are important in suspected cases. We report a 54-year-old man, who sustained a number of injuries including blunt chest injury as a consequence of a road traffic accident. Electrocardiography monitoring over a 48 h period demonstrated sequential degrees of conduction system block coupled with a temporary cardio-version from persistent atrial fibrillation to sinus rhythm, suggesting coincident pulmonary vein contusion.
