Echelon Pt 2 Rhythms Questions and
Answers | 100% Pass
ECG strip that shows regular atrial rhythm, an atrial rate greater than ventricular rate
(some QRS complexes are dropped) and a constant PR interval when the atrial and
ventricular complexes appear together would most likely be identified as what rhythm? -
Answer✔✔-2nd degree block type II
Why is the R-on-T premature ventricular complex (PVC) of major concern? -
Answer✔✔-The ventricles are being stimulated during the relative refractory period
What are premature ventricular complexes (PVCs) that arise from several irritable sites
called?
A. Unifocal premature ventricular complexes
B. Multifocal premature ventricular complexes
C. Premature ventricular complex couplet
D. Trigeminal premature ventricular complexes - Answer✔✔-B. Multifocal premature
ventricular complexes

A. 2 seconds
B. 30 seconds
C. 120 seconds
D. 300 minutes - Answer✔✔-B. 30 seconds

The P wave is never hidden in which one of the following rhythms?
A. 2nd degree heart block type II
B. 3rd degree heart block
C. Junctional
D. Supraventricular tachycardia (SVT) - Answer✔✔-A. 2nd degree heart block type II
What rhythm is characterized by a conduction block between the atria and ventricles
resulting in some nonconducted P waves (QRS complex drops) but fixed PR intervals
when the P wave and QRS complex appear together?
A. Bundle branch block (BBB)
B. 2nd degree heart block type II
C. 3rd degree heart block at bundle branch block level
D. Idioventricular rhythm (IVR) - Answer✔✔-B. 2nd degree heart block type II
Which is a key to differentiating 2nd degree block type I from type II?
A. PR intervals
B. P waves
C. Rate
D. Rhythm
Correct - Answer✔✔-A. PR intervals
Which is the correct intervention sequence for ventricular fibrillation?
A. Access the patient; initiate CPR; administer epinephrine
B. Access the patient; initiate CPR; defibrillate ASAP
C. Access the patient; defibrillate; intubate
