1. Systematic Approach to Wide QRS Tachycardia Salah Atta, MD, Lecturer of Cardiology Department of Cardiology, Assiut University Hospitals Weekly Department meeting 2004

2. Aberration means BBB either functional or fixed. Also non specific intraventricular Conduction delay may be 2ry to electrolyte disturbance or myocardial ischaemia. (Pre-excited tachycardias)

16. VT versus SVT in V1, V6 when V1 is positive i.e RBBB pattern

20. VT versus SVT in V1, V6 when V1 is positive i.e RBBB pattern V1 V6 VT SVT

26. So collectively the morphology criteria suggestive of VT includes: Abnormal or extreme Axis.

35. N.B This algorithm was found to be specially not applicable to the Idiopathic VT.

36. It may seem smart to diagnose SVT with aberration when the others suggest VT but it is wise not to do so unless sure.

37. Thank you
