How do you determine whether the atrial rhythm on an ECG tracing is regular or
irregular? - answer Compare R-R intervals from one complex to another.
The QRS complex represents: - answer Depolarization of the ventricles.
Which of the following would be considered normal for a PR interval? - answer0.16
seconds
Which of the following would NOT be an expected P wave configuration in PACs? -
answerP wave hidden in the QRS complex.
Which of the following correctly describes multifocal atrial tachycardia? - answerAtrial
and ventricular rhythms are irregular.
Which of the following ECG characteristics distinguish atrial flutter from other atrial
dysrhythmias? - answer The saw tooth or picket fence appearance before the QRS.
Which of the following is NOT a characteristic of atrial fibrillation? - answer Presence of
a saw tooth baseline.
The inherent rate of impulse formation in the junctional tissue is: - answer40-60 bpm
Which of the following would NOT be an expected P wave configuration in junctional
rhythm? - answerInverted, before QRS complex, 0.16 seconds
You evaluate a monitor strip and find that the patients QRS interval is 0.14 seconds.
You know that patient is: - answerIndicative of a slowed ventricular depolarization.
Which of the following usually produces an irregular ventricular rhythm? - answerAtrial
fibrillation.
The PR interval in 1° heart block: - answerIs constant and greater than 0.20 seconds in
duration.
An irregular ventricular rhythm is usually produced with: - answer2° AV block type 1
(wenkebach)
The dysrhythmia characterized by cycles in which the PR interval progressively
lengthens until a QRS complex is dropped is called: - answer2° heart block type 1
