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
