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.

Question 2

2.  Interpret the 12 lead EKG below:

A.  Anterior Lateral Ischemia

B.  Anterior Lateral Infarction

C.  Posterior Wall Infarction

D.  Left Bundle Branch Block

Answer and Explanation 1

1. A left axis deviation is the correct answer.  When trying determine the appropriate axis you need to look at the positive or negative deflection of the QRS of Leads AVF and I.  Normal axis =positive deflection in lead I, and positive deflection lead AVF.  Left Axis Deviation=Negative deflection of AVF and Positive deflection of lead I.  Right Axis Deviation=negative deflection of lead I and positive deflection of lead AVF.  Extreme Right Axis Deviation=negative deflections of both lead I and lead AVF.

Question 1

1. Which of the following is the best interpretation of the EKG listed below?

A.  Left Axis Deviation

B.  Right Axis Deviation

C.  Normal Axis

D.  Extreme Right Axis Deviation
