Ventricular tachycardiaCreated OnApril 17, 2020Last Updated OnApril 17, 2020byadmin You are here: Main ECG Ventricular tachycardia < All Topics Table of Contents A differential of wide complex tachycardia,Regular wide complex tachycardia is ventricular tachycardia (VT) until proven other wise. When in doubt, it is always ventricular tachycardia (VT). Exception: if you have a baseline and the QRS complexes are the same during sinus rhythm ECG features: Very broad complexes (>160ms) Absence of typical RBBB or LBBB morphology Produces uniform QRS complexes within each lead — each QRS is identical (except for fusion/capture beats) AV dissociation (P and QRS complexes at different rates) Capture beat: when sinus node “captures” the ventricles producing narrow-complex beat) Fusion beat: caused by colliding current from different sources in the ventricles Sustained VT Rate > 120-130 Lasts at least 30 seconds or produces hemodynamic instability Treatment with antiarrhythmic medications or electrical cardioversion Non-sustained VT Rate > 120-130 Lasts < 30 seconds, no associated hemodynamic instability Key to treatment is to look for and treat underlying cause Cardiac ischemic, hypoxia, electrolyte abnormalities, PE, etc. Cardiac ischemia may induce sustained or non-sustained monomorphic VT in the presence of a myocardial scar *We do not own this youtube video, it’s for sharing purpose
