Answers


01.  d. Third degree block
02.  d. Idioventricular rhythm
03.  a. Sinus bradycardia with run of polymorphic ventricular tachycardia (R-on-T PVC leading to VT)
04.  c. Sinus tachycardia
05.  c. Monomorphic ventricular tachycardia
06.  a. Atrial fibrillation with slow ventricular response
07.  a. NSR with bigeminal PVCs.   Alternating PVCs and fusion beats.  Very unusual!
08.  d. Ventricular paced with demand atrial pacing
09.  d.  Electrical pacemaker interference
10.  c. Junctional rhythm
