1. The faster discharging rate of the AV junction in an accelerated junctional rhythm may be due to:

a. Increased automaticity of the AV junction

b. Blockage of the parasympathetic nervous system response

c. Increased excitation of the internodal pathways

d. Increased excitation of the sinoatrial node

2. Paroxysmal junctional tachycardia is often more appropriately called paroxysmal supraventricular tachycardia, since it may be difficult to distinguish this rhythm from paroxysmal atrial tachycardia due to the rapid rate.

a. True b. False
