The answer to question 1  A
The rhythm strip shows an accelerated junctional rhythm.

The answer to question 2  C
Toxicity or excess of digitalis is a common cause of junctional dysrhythmias.

The answer to question 3  A PVC is premature and occurs before the next expected sinus beat. A ventricular escape beat is late, occurring after the next expected sinus beat.

The answer to question 4  SA node: 60 to 100 beats/min
AV junction: 40 to 60 beats/min
Ventricles: 20 to 40 beats/min
