Which of the following rhythms has a constant PR interval for all conducted beats?

A. In 2nd-degree AV heart block, type II,

 

a. the P waves are all the same.

b. a QRS complex follows each P wave.

c. the pacemaker site is in the AV junction.

d. the ventricular rate is less than 40 beats per minute.

B. Which of the following rhythms has a constant PR interval for all conducted

beats?

a. 2nd-degree AV heart block, type I

b. 3rd-degree AV heart block

c. 2nd-degree AV heart block, type II

d. All of the above

C. The difference between 2nd-degree AV heart block, type I, and type

II is that

a. in type I, the PR intervals are progressively longer until a QRS complex

is dropped and the cycle starts over again.

b. the ventricular rate in type II is usually greater than 60 beats per minute.

c. in type II, the P waves appear to march right through the QRS complexes.

d. in type II, there appears to be a pattern to the irregularity.

D. An ECG rhythm that has no correlation between P waves and QRS

complexes

is known as (LO 16.5)

a. 1st-degree AV heart block.

b. 2nd-degree AV heart block, type II.

c. 2nd-degree AV heart block, type I.

d. 3rd-degree AV heart block.
