A major United Kingdom corporation is conducting a free wellness screening clinic for their employees. The 40-year-old male below relates a history of frequent debilitating "dizzy spells". Your interpretation/advice is: (Choose only one)
A..... Early transition. This could represent a posterior infarction, but is most likely secondary to the WPW (pseudoinfarction).
B..... Wolff-Parkinson-White (WPW) syndrome. It meets the triad criteria as follows: 1. QRS duration > 0.10 sec. 2. Short PR < 0.12 sec. 3. Presence of Delta Waves.
C..... Significantly wide Q-waves in Leads III, avF consistent with inferior infarction but most likely secondary to the WPW (pseudoinfarction).
D..... R > 12 mm Lead avL. Meets the voltage criteria of LVH but most likely is simply secondary to the WPW (pseudo-LVH).
E..... Short PR interval, but otherwise does not satisfy the criteria of WPW.
F..... Incomplete LBBB.
G..... Lown-Ganong-Levine Syndrome.
H..... None of the above.
I..... A, B, C and D only.
