a. Normal sinus rhythm
5.
a. Normal sinus rhythm with 1st degree block
6.
a. Sinus bradycardia with atrial ectopy
7.
a. Bradycardia with 1st degree AV block
8.
a. Sinus bradycardia
b. Junctional rhythm
9.

a. Atrial paced
10.
a. Sinus tachycardia with atrial ectopy
Answers
1.
d. 1st degree AV block. The PR interval is 0.26 seconds
2.
b. Accelerated idioventricular rhythm. This rhythm has all the characteristics of a ventricular paced rhythm (wide, negative, QRS complex with a positive ST segment) except that I do not see any pacer spikes.
3.
c. Atrial fibrillation. The rhythm is irregular and without P waves.
4.
a. Normal sinus rhythm. There is also some ST segment depression.
5.
b. Sinus bradycardia
6.
b. Normal sinus rhythm with bigeminal PVCs. The strip terminates with a multifocal couplet
7.
c. Accelerated junctional rhythm. There is a downward sloping ST segment. May be significant for ischemia.
8.
c. Agonal rhythm. An agonal rhythm is slower ( < 20 bpm) and less organized than an idioventricular rhythm. The waveform looks more like a sinusoidal wave.
9.
a. Atrial paced. Atrial pacer spikes precede each P wave.
10
c. Sinus rhythm with trigeminal PJCs. No P waves are associated with the ectopic beats. The QRS complex is narrow with some slurring of the S wave, similar to the sinus beats.
