Answers


1.

b. Idioventricular rhythm.   By process of elimination, it is not bradycardia with sinus arrhythmia because there are no P waves.  It is not a complete heart block because there are no P waves.  It is not a junctional rhythm because the QRS complex is wide, not narrow.   So it must be an idioventricular rhythm.

2.

b. 2nd degree heart block type II.  The PR interval on the conducted beats is fixed.    A PVC follows the first complex.   Thereafter, a nonconducted beat follows each complex.

3.

 a. Atrial flutter with variable rate.   The flutter waves are more apparent in lead V1.   The rhythm varies between a 3:1 and 4:1 conduction which accounts for the variation in the rhythm and rate.

4.

d. Biventricular paced.  There are two ventricular pacer spikes present.

5.

d. Idioventricular rhythm.    The rate is around 44.   There are no P waves present.  The QRS complex is wide which is indicative of a rhythm of ventricular origin.

6.

a. 3rd degree AV block.   Complete AV dissociation with the atria and ventricles beating at different rates.  Some P waves are buried within the QRS complex (1st complex) and the T waves (3rd complex).

7.

d. Sinus rhythm with multifocal PVCs.   A compensatory pause follows the PVCs.   There is also a PAC present, the 8th complex.  A multifocal couplet is seen at the end of the rhythm strip.

8.

c. Ventricular trigemeny.   A PVC occurs every 3rd beat.  A compensatory pause follows each PVC.

9.

d. Sinus arrhythmia with an occasional PVC.  Notice the unusual shape of the P wave.  It is split across the top.   The first small hump represent right atrial depolarization and the second little hump represent left atrial depolarization.

10.

c. Sinus arrhythmia.    The rhythm is irregular.   No ectopy is noted.
