Dyspnea
Tachycardia
Which assessment data Chest pain
suggests the presence of Confusion
a dysrhythmia? Lightheadedness
Palpitations
Syncope
A nurse is caring for a Third-degree heart block <
client two days after a Ventricular tachycardia
myocardial infarction. Atrial fibrillation
When analyzing the Sinus bradycardia
electrocardiogram (ECG)
pattern, the nurse
analyzes the following:
atrial rate 82 bpm and
regular
ventricular rate 46 bpm
and regular
P wave and QRS
complexes are normal
no relationship between P
wave and QRS complex
What dysrhythmia does
this identify?

When caring for a client depolarizes
with ventricular fibrillation, SA node
the nurse understands that
defibrillation _________________
the cells of the
myocardium to allow the
______________ to resume
pacemaker functions.
Atrial and ventricular rate normal. One P wave for
each QRS complex. Prolonged PR interval.
First-degree Constant atrial rate, constant ventricular rate. P wave
has no relationship to QRS complexes. Inconsistent
Third-degree PR interval.
Second-degree, Type II Constant atrial rate, irregular ventricular rate. More P
waves than QRS complexes. PR interval constant.
Second-degree, Type I
Constant atrial rate, irregular ventricular rate.
Progressive lengthening of PR interval until QRS
complex is dropped.
Fixed-mode pacemakers asynchronous
fire in a/an ___________ activity
pattern. The rate does not synchronous
change with _____________. heart rate
Demand-mode
pacemakers fire in a/an
____________ pattern. The
device only fires when the
_________
is below the set threshold.
