Question 37

37.  Please identify the abnormality seen on the EKG listed below:

A.  Sinus block
B.  Sinus arrhythmia
C.  First degree AV Block
D.  Premature atrial contraction

Answer 36

36.  Choice B is the correct answer.  Atrial flutter is characterized by a regular saw tooth pattern between QRS complexes because the ectopic focus is coming from the same area in the atria.  Atrial fibrillation has an irregular baseline because the ectopic focus comes from multiple areas in the atria.  Paroxysmal atrial tachycardia is narrow complex tachycardia with a rate over 150 beats per minute.  Wandering atrial pacemaker the P wave is in different shapes and positions because the pacemaker is coming from different areas.

Question 36

A.  Paroxysmal atrial tachycardia
B.  Atrial Flutter
C.  Atrial Fibrillation
D.  Wandering atrial pacemaker

Answer 35

35.  Choice C is the correct answer.  Hypercalcemia is demonstrated by a shortened QT interval.  Hypocalcemia has a long QT interval.  Hypokalemia has flattened T waves and may have a U wave.  Hyperkalemia has peaked T waves.

A.  Hyperkalemia
B.  Hypokalemia
C.  Hypercalcemia
D.  Hypocalcemia

Answer 34

34.  Choice B is the correct answer.  Bigeminy is when there is a PVC every other beat.  Trigeminy is when there is a PVC every third beat.  If there is two consecutive PVC's it is referred to as a couplet.
