Electrical Alternans
Key Points Classically associated with pericardial tamponade but seen in fewer than 30% of confirmed cases. Combination of low-voltage QRS + sinus tachycardia strongly suggests pericardial effusion/tamponade. Always perform rapid…
STAT ECG Diagnoses: the differentials to consider when dealing with ST segment elevation and an impressive syndrome
A 61-year-old woman presents the ED for evaluation of a possible acute stroke. She woke up unable to walk due to bilateral lower extremity weakness and is now also feeling…
Potpourri of cases: the most common ECG findings in pulmonary embolism, electrical alternans, and so much more!
A 72-year-old woman presents the ED with atypical chest pain. She is found to be mildly tachycardic. The following ECG is obtained:
STAT ECG Diagnoses: is this ST segment elevation due to early repolarization or a large STEMI?
A 38-year-old male presents to the ED with acute chest pain. The following ECG is obtained:
ECG Basics & Fundamentals: electrical alternans is present in less than 1/3 of patients with proven cardiac tamponade
A 56-year-old woman with history of breast cancer presents to the ED with chest pain and dyspnea. She is found to be afebrile, tachypneic, and tachycardic with a normal blood…
