What are you worried about with 3rd degree heart block? -
ANSWER-Perfusion
What should be anticipated for 2nd degree and 3rd degree heart
block? - ANSWER-Pacemaker and dopamine
What is the difference between cardioversion and defib? -
ANSWER-Cardioversion: has a synchronized shock that is
delivered to the QRS complex, lower amount of joules used, not
done with CPR, treatment for atrial dysrhythmias, SVT, V-tach
with a pulse, can also be used for A-fib/A-flutter RVR
Defib: asynchronous, stops all electrical activity of the heart
allowing the SA node to take over and reestablish a rhythm,
higher amount of joules used, resume CPR after shock, used on
unstable patients such as V-ach or V-fib, done on rhythms with no
pulse

What is the memory trick for cardioversion and defib? - ANSWER-
Cardioversion are Carefully planned
If it has a V (V-tach or V-fib) give them the D (Defib)
What is syncope? - ANSWER-Fainting

recognition and treatment

What is ectopy? What are examples? - ANSWER-An extra beat
when the heart contracts too soon
Ex: premature atrial contraction, premature ventricle
contraction
How does ectopy occur? - ANSWER-Caffeine
Electrolyte imbalance
What are pre considerations for cardioversion and defib? -
ANSWER-Client with A-fib must receive anticoagulation 4-6
weeks before cardioversion to prevent dislodgment of thrombi
Digoxin is held for 48 hrs before cardioversion
What are intra considerations for cardioversion and defib? -
ANSWER-Administer sedation as prescribed for cardioversion
