Answer and Explanation 5

5.  B is the correct answer.  This EKG strip shows the P wave (the pacemaker) wandering around in different positions.  The PR interval is not consistently long so it is not a first degree AV block.  Junctional rhythm shows P waves inverted occur before, during or after the QRS complex.  There are no PVC's

Question 5

5.  Please interpret the EKG strip below:

A.  First Degree AV Block

B.  Wandering Atrial Pacemaker

C.  Junctional Rhythm

D.  Premature Ventricular Contractions

Answer and Explanation 4

11.  B is  the correct answer.  Diffuse ST elevation in all leads without reciprocal changes is consistent with pericarditis.  Hyperkalemia causes peaked T waves but not ST elevation.   You see Delta Waves in Wolf Parkinson White Syndrome.

Question 4

4.  Please interpret the EKG below:

A.  Brugada Syndrome

B.  Pericarditis

C.  Wolf Parkinson White Syndrome

D.  Hyperkalemia

Answer and Explanation 3

3.  C is the correct answer.  This is Wolf Parkinson White Syndrome.  This is demonstrated by the delta waves seen in leads I, AVL, and leads V2-V6.  There is no evidence of Junctional Rhythm because the P Waves are normal. There is no sick sinus syndrome.  All of the P waves conduct through.  Brugada Syndrome because there is no J point elevation by negative T wave deflection.  This is usually observed in leads V1-V3.

Question 3

3.  Please interpret the EKG below

A.  Junctional rhythm

B.  Brugada Syndrome

C.  Wolf Parkinson White Syndrome

D.  Sick Sinus Syndrome

Answer and Explanation 2

2.  The correct answer is B anterior lateral infarction.  There is ST elevation in the anterior leads V3 and V4, as well in the Lateral Leads V5, V6, I and AVL.  There is reciprocal changes in the inferior leads AVF and III.  There is no ST depression and no evidence of a Left BBB.
