Answers


1.

Mobitz I

 c.  Mobitz I.  This is a rhythm strip from a patient that would transition in and out of a Mobitz I and sinus bradycardia.   On lead II the T waves could be misconstrued for P waves but if you measure their intervals you will find that they are not equal.

2.

Demand atrial pacing

a.  Demand atrial pacing.  There are ventricular pacer spikes for each of the QRS complexes but the atrial pacer spikes are not always present.


3.

Normal sinus rhythm with a PJC

b. Normal sinus rhythm with a PJC.  The 5th complex arises early in the cardiac cycle.  There is an inverted P wave that precedes the QRS complex.  This is characteristic of a PJC.


4.

Normal sinus rhythm with unifocal PVCs

b.  Normal sinus rhythm with unifocal PVCs


5.

Sinus bradycardia

a.  Sinus bradycardia



6.

 Atrial flutter

d.  Atrial flutter


7.

Junctional rhythm

a.  Junctional rhythm.  Negative P waves precede each QRS complex.

8.

Sinus rhythm with sinus pauses

a.  Sinus rhythm with sinus pauses


9.

Atrial fibrillation with rapid ventricular response

d.  Atrial fibrillation with rapid ventricular response.   The rate qualifies this rhythm as a supraventricular tachycardia.  However, it is very irregular which is not characteristic of SVT.


10.

Normal sinus rhythm with multifocal PVCs

a.   Normal sinus rhythm with multifocal PVCs.   You can also say that it is NSR with a 4 beat run of polymorphic VT.
