PR intervals
P waves
Rate
Rhythm - ✔✔PR intervals
✔✔Which heart block is considered normal in some individuals?
Normal sinus rhythm (NSR) with bundle branch block
2nd degree block Type I
Normal sinus rhythm (NSR) with 1st degree block
2nd degree block Type II - ✔✔Normal sinus rhythm (NSR) with 1st degree block

rhythms? (Select all that apply)
Asystole or PEA
, Idioventricular rhythm (IVR)
Pulseless ventricular tachycardia
Ventricular fibrillation - ✔✔Asystole or PEA
Idioventricular rhythm (IVR)
✔✔An ECG strip that shows a regular atrial rhythm, an atrial rate greater than the
ventricular rate (some QRS complexes are dropped), and a constant PR interval when
the atrial and ventricular complexes appear together would most likely be identifited as
what rhythm?
2nd degree block Type II
Sinus rhythm with bundle branch block
2nd degree block Type I

True
False - ✔✔True

Occurs when the supraventricular pacemaker fails to fire an impulse
The rate of this rhythm is not adequate to sustain life
The PR interval in this rhythm is within normal range
This rhythm generates wide, bizarre QRS complexes - ✔✔The PR interval in this
rhythm is within normal range
✔✔What does the information found in the last 0.04 seconds from the J point back into
the QRS complex differentiate?
Degree of heart block
Origin of heart block
Right bundle branch block from left bundle branch block
Root cause of bundle branch block - ✔✔Right bundle branch block from left bundle
branch block
✔✔Ventricular rhythms have a QRS of 0.10 or greater due to which of the following?
Atypical ventricular repolarization
Ventricles are stimulated asynchronously
Ventricles depolarize early
Ventricular irritability - ✔✔Ventricles are stimulated asynchronously
✔✔What are premature ventricular complexes (PVCs) that arise from several irritable
sites called?
Unifocal premature ventricular complexes
Multifocal premature ventricular complexes
Premature ventricular complex couplet
