STAT ECG Diagnoses: a review of the differentials to consider when dealing with wide complex tachycardias and when antiarrhythmic medications can be harmful
A 41-year-old female is brought into the ED by EMS unresponsive with unknown past medical history. She is found to be febrile, normotensive (126/78), tachycardic (120s-150s), tachypneic (30s with a…
STAT ECG Diagnoses: knowing what you are looking for when differentiating the different types of regular wide complex tachycardias
A 79-year-old male is brought into the ED by EMS with palpitations and lightheadedness while doing light yardwork. He is found to have a wide complex tachycardia at 155 bpm,…
STAT ECG Diagnoses: the great immitator strikes again in a case of wide complex tachycardia
A 48-year-old female presents to the ED 2 days after Thanksgiving with complaints of severe generalized weakness, palpitations, and chest discomfort. She is noted to be tachycardic and tachypneic at…
Differential Diagnoses: wide QRS, right axis deviation, tall R wave in V1
HPI: A 76-year-old woman presents to the ED with dyspnea and a syncopal episode. History is limited because the patient is listless and confused. The following ECG was obtained: Case…
Wide Complex Tachycardias: ventricular tachycardia (VT) mimics
HPI: A 71-year- old woman with PMHx of HTN and “irregular heart rhythm” presents to the ED with weakness, lightheadedness, and occasional palpitations. She does not know the name of her medications…
Differential DIagnoses: right axis deviation, prolonged QT interval, and a wide QRS
A 46-year-old man with no known past medical history presents to the ED with recurrent witnessed seizures, actively seizing. The seizures are not responding to treatment with benzodiazepines. The following…
