Shock first and ask questions later?
An elderly woman with a past medical history of hypertension, diabetes, and Parkinson’s disease presents to the ED with hip pain after a fall. Her blood pressure and mental status…
Wide Complex Tachycardias: clues to VT mimics when the heart rate is too slow or the QRS complexes are too wide
An unknown aged female is being transported to the emergency department by EMS for altered mental status. She is agitated and slurring words. Vitals: 98/65, RR 24, HR 162. The…
Wide Complex Tachycardias: beware the many mimics of ventricular tachycardia
A 73-year-old woman with PMHx of HTN, DM, HLD presents to the emergency department with 2 days of vomiting, malaise, and indigestion with chest discomfort. The following ECG is obtained:
Post-cardiac arrest ECGs: evaluation of ischemia, dysrhythmias, and their mimics
A 55-year-old man presents to the emergency department with nonspecific chest pain. 20 minutes into his evaluation he is found to be diaphoretic and unresponsive in cardiac arrest with ventricular…
