Svt With Lbbb Vs Vt. However the qrs is not very wide at all. This is svt with a lbbb.
Additionally we know that many patients have underlying bundle branch block including bifascicular block at baseline. I will discuss these two mechanisms below primarily for the sake of completeness and is not intended to. You can try applying the brugada criteria to the ecg.
Development mechanisms of ventricular tachycardia.
Ventricular tachycardia occurs via two common mechanisms. Yes vt sensitivity 0 987 specificity 0 965 no svt with aberrant conduction sensitivity 0 965 specificity 0 987 determine if you have a lbbb morphology dominant s wave in v1 or a rbbb morphology dominant r wave in v1 then use the appropriate section below to help differentiate. It might degenerate to ventricular fibrillation and death. The ecg below shows a lbbb morphology with a rapid rate.
