Objectives: The ability to interpret a 12-lead electrocardiogram (ECG) is an essential skill in inpatient and outpatient settings. In medical school, this skill is generally taught during the Internal Medicine clerkship. Blended learning is a pedagogical tool that combines different modes of information delivery, models of teaching, and learning styles…
Abstract:An 86-year-old man presented with sudden onset of dyspnea during hospitalization. Initial electrocardiography (ECG) showed poor R-wave progression of precordial leads with elevation of troponin I. Tension pneumothorax was subsequently diagnosed and the ECG returned to normal after resolution of clinical compromise.
Perioperative myocardial infarctions occur in 1 to 4% of unselected noncardiac surgical patients, and are associated with high mortality. Detection of these events can be challenging, because ‘typical’ symptoms of myocardial ischemia may not be present or may be masked in the perioperative period. Therefore, surveillance by means of intraoperative…
Fulminant myocarditis is an uncommon diagnosis characterized by cardiac failure preceded by symptoms of a viral illness. Presentation can frequently mimic acute myocardial infarction. The electrocardiographic changes are frequently nonspecific, but include ST segment elevation and T wave changes, as well as conduction abnormalities. We report the case of a…
