Ventricular tachycardia vs. SVT with aberrant conduction
Results:
Wide Complex Tachycardias: using modified ECG leads to distinguish ventricular tachycardia from supraventricular tachycardias (VT vs. SVT)
A 60-year-old man presents to the emergency department with left sided chest pain and lower extremity edema. Initial vitals: HR= 155, BP = 120/96, RR = 22, SpO2 = 90%,…
Wide Complex Tachycardias: can ECG algorithms safely rule out ventricular tachycardia in the emergency department?
A 45-year-old man with PMHx of hypertension, obesity, and tobacco use presents to the ED with palpitations. Symptoms have been intermittent throughout the day with an associated episode of syncope….
STAT ECG Diagnoses: using the ECG in cases of wide complex tachycardia to diagnose ventricular tachycardia (VT)
A 25-year-old otherwise healthy woman with no significant PMHx presents to the ED with palpitations. The following ECG was obtained:
