Which of the following is NOT a differential Dx for irregular wide complex tachycardia?
A. A-fib with WPW
B. Polymorphic V-tach
C. Orthodromic AVRT (AV Nodal Reentrant Tach.)
A
C. Orthodromic AVRT
Orthodromic (“orthodromic”-“straight”) AVRT travels normally from SA to AV. Upon reaching the AV node, the bundle of Kent returns the AP to the SA node. This normal conduction produces a REGULAR narrow complex rhythm.
