d.  Normal sinus rhythm changing to ventricular tachycardia


9.

a.   Normal sinus rhythm with a triplet of PVCs
b.   Normal sinus rhythm with trigeminal PVCs
c.   Normal sinus rhythm with consecutive PACs
d.   Normal sinus rhythm with sustained ventricular tachycardia


10.

a.  Sinus rhythm with runs of ventricular tachycardia
b.  Sinus rhythm with runs of ventricular fibrillation
c.  Sinus rhythm with runs of supraventricular tachycardia
d.  Sinus rhythm with frequent multifocal PVCs


Answers


1.    b.  Atrial fibrillation with a PVC
2.    a.  Normal sinus rhythm with bigeminal PVCs and a couplet
3.    c.  Biventricular paced with a PVC
4.    d.   AV dissociation.  The P-P interval is irregular but the R-R interval is regular in this rhythm.  There is complete AV dissociation.
5.    d.  Demand ventricular paced
6.    c.  Accelerated idioventricular rhythm
7.    b.  2nd degree AV block type I.   There is progressive elongation of the PR interval but the dropped beat is not seen.    So what would we call this rhythm?   AV dissociation?  
8.    c.  Normal sinus rhythm changing to junctional tachycardia
9.    b.  Normal sinus rhythm with trigeminal PVCs
10.  a.  Sinus rhythm with runs of ventricular tachycardia
