case_images: Emergency electrocardiograms all showed Broad QRS Tachycardia (WCT), as shown in Figures 1, 2, 3. Figures 1, 2, 3 WCT all showed the pattern of Right Bundle Branch Block (CRBBB), and the QRS wave was sharp in the front, the excitation rate (Vi) of the initial 40 ms/QRS wave group terminal 40 ms excitation rate (Vt) > 1, using common WCT differential methods such as aVR lead method (aVR lead Vi/Vt > 1) (Vereckei et al. ), limb lead algorithm (not consistent with VT patterns) (Chen et al. ), Basel algorithm (scoring zero due to the absence of structural heart disease and the time to first peak in Leads II and aVR < 40 ms) (Moccetti et al. ) diagnosed as Supraventricular Tachycardia (SVT).
