Answers


1.    d.   Accelerated idioventricular rhythm changing to asystole
Accelerated idioventricular rhythm changing to asystole
The rhythm appears to be ventricular tachycardia but the rate is less than 100bpm so this makes it an accelerated idioventricular rhythm.
2.    a.  Junctional rhythm
Junctional rhythm
Notice the retrograde P waves that follow the QRS complex.
3.    b.   Bradycardia with sinus arrhythmia
4.    b.   Sinus tachycardia with a PAC
5.    d.   Ventricular paced with a triplet of PVCs
6.    d.   Ventricular paced with multifocal PVCs
7.    d.   Supraventricular tachycardia
8.    c.   Ventricular tachycardia
9.    c.   Atrial fibrillation with run a run of ventricular tachycardia
10.   a.  Normal sinus rhythm with unifocal PVCs
