1. WIDE COMPLEX TACHYCARDIA
Presented by… Dr Amit Badgal
Moderator..DR SANJEEV AGGARWAL

2. Wide complex tachycardia:
12 lead ECG with rhythm strip…primary
tool.
Heart rate > 100bpm
QRS duration > 0.12seconds
≥3 consecutive beats

4. The algorithm proposed by the ACC/AHA/ESC guideline
for WCT differential diagnosis

11. ECG algorithms to differentiate wide
QRS-complex tachycardias

12. The algorithm of Brugada working group devised for
distinguishing VT from Pre-excited Tachycardia

13. The aVR Vereckei algorithm

14. Velocity ratio between initial and terminal 40 ms of
the QRS complex(Vi/Vt )in lead aVR
<1suggesting ventricular tachycardia
>1 suggests SVT (Vereckei
et al.).
