Stimulation of parasympathetic nerve fibers typically
results in what action? - CORRECT ANSWER✔️ Slowed
conduction through the atrioventricular (AV) node
The contribution of blood that is added to the ventricles
and results from atrial contraction is called: - CORRECT
ANSWER✔️ atrial kick
Semilunar Valves include: - CORRECT ANSWER✔️
pulmonary valve and aortic valve

ANSWER✔️ LAD and Cx branches
_____ cells are specialized cells of the electrical
conduction system responsible for the spontaneous
generation and conduction of electrical impulses. -
CORRECT ANSWER✔️ Pacemaker
,The absolute refractory period beings with.... - CORRECT
ANSWER✔️ begins with the onset of the QRS complex
and terminates at approximately the apex of the T wave
T/F: The QT interval represents the time from initial
depolarization of the ventricles to the end of ventricular
repolarization - CORRECT ANSWER✔️ true
How do you determine whether the atrial rhythm on an
ECG tracing is regular or irregular? - CORRECT
ANSWER✔️ compare P-P intervals
Which ECG leads use two distinct electrodes, one of
which is positive and the other negative? - CORRECT
ANSWER✔️ leads I, II, and III
In sinus arrhythmia, a gradual decreasing of the heart rate
is usually associated with? - CORRECT ANSWER✔️
expiration
An ECG rhythm strip shows a ventricular rate of 46 bpm, a

duration of 0.06 second, and one upright P wave before
each QRS. This rhythm is: - CORRECT ANSWER✔️
sinus bradycardia
SA block is a disorder of ______, and sinus arrest is a
disorder of impulse _______. - CORRECT ANSWER✔️
SA block is a disorder of conduction
Sinus arrest is a disorder of formation
, Signs and symptoms experienced during a
tachydysrhythmia are usually primarily related to: -
CORRECT ANSWER✔️ decreased ventricular filling time
and stroke volume
Example that reflects ectopic (latent) pacemaker: -
CORRECT ANSWER✔️ the AV junction and ventricles
A wandering atrial pacemaker rhythm with a ventricular
rate of 60 to 100 bpm may also be referred to as: -
CORRECT ANSWER✔️ multiform atrial rhythm
The most common type of supraventricular tachycardia
(SVT) is? - CORRECT ANSWER✔️ AVNRT-- AV nodal
reentrant tachycardia
If the onset or end of paroxysmal atrial tachycardia or
paroxysmal supraventricular tachycardia (PVST) is not
observed on the ECG, the dysrhythmia is called: -
