Chapter 07: Heart Blocks

Test Bank

 

TRUE/FALSE

 

  1. The ventricular rhythm is regular in second-degree AV block type I.

 

ANS:  F

With second-degree AV block type I, the ventricular rhythm is irregular. The atrial rate is regular (i.e., Ps plot through on time). Grouped beating may be present.

 

OBJ:   Describe the ECG characteristics, possible causes, signs and symptoms, and emergency management for second-degree AV block type I.

 

  1. The QRS complex associated with a third-degree AV block is always wide.

 

ANS:  F

The site of block in a third-degree AV block may be the AV node or, more commonly, the bundle of His or the bundle branches. A secondary pacemaker (either junctional or ventricular) stimulates the ventricles; therefore the QRS may be narrow or wide, depending on the location of the escape pacemaker and the condition of the intraventricular conduction system.

 

OBJ:   Describe the ECG characteristics, possible causes, signs and symptoms, and emergency management for third-degree AV block.

 

MULTIPLE CHOICE

 

  1. In 2:1 AV block, the PR interval _____.
a. shortens
b. lengthens
c. is absent
d. remains constant

 

 

ANS:  D

Second-degree 2:1 AV block is characterized by P waves that are normal in size and shape, but every other P wave is not followed by a QRS. The atrial rate is twice the ventricular rate. The PR interval for the conducted beats is constant.

 

OBJ:   Describe 2:1 AV block and advanced second-degree AV block.

 

  1. The PR interval of a first-degree AV block _____.
a. is constant and less than 0.12 seconds in duration
b. is constant and more than 0.20 seconds in duration
c. is generally progressive until a P wave appears without a QRS complex
d. gradually decreases in duration until a P wave appears without a QRS complex

 

 

ANS:  B

A first-degree AV block is present when there is a 1:1 relationship between P waves and QRS complexes and the PR interval is prolonged (i.e., more than 0.20 seconds) and constant.

 

OBJ:   Describe the ECG characteristics, possible causes, signs and symptoms, and emergency management for first-degree AV block.

 

  1. An ECG rhythm strip shows a regular ventricular rhythm at a rate of 30 beats/min, more P waves than QRS complexes (the P waves occur regularly), a variable PR interval, and a QRS duration of 0.14 seconds. This rhythm is _____.
a. 2:1 AV block
b. third-degree AV block
c. second-degree AV block type I
d. second-degree AV block type II

 

 

ANS:  B

With a third-degree block, the ventricular and atrial rhythms are regular; however, AV dissociation is present. The ventricular rate is determined by the origin of the escape rhythm. Based on the description provided (i.e., a QRS duration of 0.14 seconds and a ventricular rate of 30 beats/min), the escape pacemaker is probably ventricular in origin. P waves are normal in size and shape, but some P waves are not followed by a QRS complex. There is no true PR interval because the atria and the ventricles beat independently of each other. The QRS may be narrow or wide, depending on the location of the escape pacemaker and the condition of the intraventricular conduction system.

 

OBJ:   Describe the ECG characteristics, possible causes, signs and symptoms, and emergency management for third-degree AV block.

 

  1. A 2:1 AV block is characterized by _____ intervals.

ANS:  C

Second-degree 2:1 AV block is characterized by regular P-P and R-R intervals. P waves are normal in size and shape, but every other P wave is not followed by a QRS. The atrial rate is twice the ventricular rate.

 

OBJ:   Describe 2:1 AV block and advanced second-degree AV block.

 

  1. Second-degree AV block type II is characterized by _____ intervals.
a. irregular P to P
b. irregular R to R
c. regular P to P intervals and regular R to R
d. irregular P to P intervals and irregular R to R

 

 

ANS:  B

With second-degree AV block type II the ventricular rhythm is irregular. There are more P waves than QRS complexes and the P-P interval is regular. P waves are normal in size and shape, but some P waves are not followed by a QRS complex. The PR interval may be within normal limits or prolonged, but it is constant for the conducted beats; the PR intervals before and after a blocked P wave are constant.

 

OBJ:   Describe the ECG characteristics, possible causes, signs and symptoms, and emergency management for second-degree AV block type II.

 

  1. Second-degree AV block type I is characterized by _____ intervals.

b. regular R to R
c. regular P to P intervals and irregular R to R
d. irregular P to P intervals and irregular R to R

OBJ:   Describe the ECG characteristics, possible causes, signs and symptoms, and emergency management for second-degree AV block type I.

 

  1. In second-degree and third-degree AV blocks, _____.
a. P waves occur regularly
b. every other P wave is dropped
c. P waves are periodically dropped
d. there are more QRS complexes than P waves

 

 

ANS:  A

In second-degree and third-degree AV blocks, there are more P waves than QRS complexes and the P waves occur regularly.

 

OBJ:   Describe the ECG characteristics, possible causes, signs and symptoms, and emergency management for third-degree AV block.

 

  1. In second-degree AV block type I, the PR interval _____.
a. shortens
b. is absent
c. is inconstant
d. remains constant

 

 

ANS:  C

In second-degree AV block type I, the PR interval is inconstant and the PR interval after a nonconducted P wave is shorter than the interval preceding the nonconducted beat.

Although progressive lengthening is a phrase that was used for many years to describe the behavior of the PR intervals associated with second-degree AV block type I, use of this terminology is no longer recommended; rather, the term inconstant or generally progressive PR intervals is recommended. Use of the term inconstant or generally progressive PR intervals is important because many type I AV blocks are atypical, missing one or more of the features of the classic Wenckebach phenomenon. For example, the second conducted PR interval after a blocked impulse may fail to show the greatest increase in length; instead, the PR interval may actually shorten and then lengthen in the middle of a grouped beating pattern. Alternately, the duration of the PR intervals may show no obvious change in the middle or for a few beats just before the end of a group.

 

OBJ:   Describe the ECG characteristics, possible causes, signs and symptoms, and emergency management for second-degree AV block type I.

 

  1. In 2:1 AV block, _____.
a. the atrial rhythm (P-P interval) is regular
b. the ventricular rhythm (R-R interval) is irregular
c. the PR interval lengthens until a P wave appears with no QRS complex
d. there is no PR interval because the atria and ventricles beat independently of each other

 

 

ANS:  A

Second-degree 2:1 AV block is characterized by P waves that are normal in size and shape, but every other P wave is not followed by a QRS. The atrial rate is twice the ventricular rate.

 

OBJ:   Describe 2:1 AV block and advanced second-degree AV block.

 

  1. In third-degree AV block, _____.
a. the atrial rhythm (P-P interval) is irregular
b. the ventricular rhythm (R-R interval) is irregular
c. there is no PR interval because the atria and ventricles beat independently of each other
d. the PR interval after a nonconducted P wave is shorter than the interval preceding the nonconducted beat

 

 

ANS:  C

In third-degree atrioventricular (AV) block, both the atrial and ventricular rhythms are regular, but the atria and ventricles beat independently; therefore the P waves that are present are unrelated to the QRS complexes (i.e., AV dissociation exists).

 

OBJ:   Describe the ECG characteristics, possible causes, signs and symptoms, and emergency management for third-degree AV block.
