Cardiac Rhythm Interpretation Exam
Questions And Answers//Latest Exam
Basic life support assessment is done by... - ANS -assessing ABCs
Primary assessment - ANS -A&O x3
auscultate lungs, assess for peripheral edema
assess for chest discomfort/palpitations
assess skin colour/temp/moisture
VS
secondary assessment - ANS -consider situation in the context of patient's hx
plan ahead
P wave represents - ANS -atrial depolarization
a normal p-wave rhythm is - ANS -present
regular
1 p-wave: 1 QRS complex
p-wave appearance - ANS -upright
identical to the other p-waves (monomorphic)
rounded
what is the atrial heart muscle doing during atrial depolarization? - ANS -contracting
, if the p-wave is absent, what part of the heart is malfunctioning? - ANS -atria
PR interval represents - ANS -time for impulse to travel from atria to the ventricles
normal length of PR interval - ANS -0.12-0.20 seconds
if a PR interval is longer than 0.20 seconds what is it called? - ANS -prolonged
QRS complex - ANS -ventricular depolarization
normal length of QRS - ANS -less than 0.12 sec
ST segment - ANS -time during which ventricles are contracting and emptying
ST segment appearance - ANS -isoelectric (flat)
T wave - ANS -ventricular repolarization
T wave normal appearance - ANS -upright, slightly rounded peak
shorter than QRS complex
QT interval represents - ANS -total time for depolarization and repolarization of ventricles
QT interval normal length - ANS -340-430 ms
sinus rhythm - ANS -originate in the SA node
normal P waves
1 P wave for every QRS
