Answer 50

50.  Choice B is the correct answer.  There is ST elevation in leads II, III, and avF not ST depression or T wave inversion consistent with an inferior wall STEMI.  This is not a normal EKG and there is no right bundle branch block on this EKG.

Question 50

50.  Please interpret the EKG below:

A.  Inferior Ischemia
B.  Inferior STEMI
C.  Normal EKG
D.  Right Bundle Branch Block

Answer 49

49.  Choice D is the correct answer.  There is complete AV dissociation.  Typical of third degree blocks the P waves and QRS complexes march out independently with calipers.  Second degree AV block type I has lengthened PR interval that drops, where as the type II has a normal PR interval that the QRS complex just drops.

Question 49

49.  Please interpret the EKG listed below:

A.  Junctional Rhythm
B.  Second Degree AV Block Type I
C.  Second Degree AV Block Type II
D.  Third Degree AV Block

Answer 48

48.  Choice B is the correct answer.  There is diffuse ST elevation throughout most of the leads of the EKG which is typical of Pericarditis.  This is not a normal EKG.  There is ST elevation in the inferior leads so there is no evidence of ischemia.

Question 48

48.  Please interpret the EKG listed below:

A.  Normal EKG
B.  Pericarditis
C.  Ventricular Tachycardia
D.  Inferior Ischemia

Answer 47

47.  Choice B is the correct answer.  This is denoted by the R and R' wave seen in leads V1 and V2.  If this was in lead V5 and V6 a left bundle branch should be considered.  This is not a premature ventricular contraction.
