Normal sinus - answer This is a ___________________________Rhythm
HR:60-100 normal
QRS complex 0.04-.12
PR interval 0.12-0.2
QT interval 0.40-0.44
0.04 – answer ekg paper
1 small box
0.2 – answer ekg paper
five small blocks equal
1 second – answer ekg paper
five large boxes equal
6 seconds - answerekg paper
30 large boxes
SA - answerP wave is the starting pulse from the ___node? located in the R atrium.
QRS complex - answerwhen the ventricals contract
The heart is resetting - answerWhat is happening during the T wave
p wave - answerrepresents atrial depolarization (contraction) usually followed by the
QRS
0.11 - answernormal length of p wave?
QRS complex - answer___________ is comprised of 3 waves
it is the ventricle depolarization (contraction)
0.04-0.12 - answernormal length of QRS complex?
pr - answer________interval is the time the impulse takes to move through the atria and
the AV node.
It begins at the P wave to the next deflection on the baseline (beginning of QRS)
, 0.12-0.2 - answernormal length of the pr interval?
ST - answer__________segment is the early repolarization of the ventricles.elevation or
depression indicates an abnormality.
lower than baseline= ichemia or injury to the heart muscle.
higher than baseline=infarct or death of the cardiac muscle and is considered worse
t wave is - answerthe repolarization of the ventricles (reset) it is concurrent with the end
of ventricular systole.
may become peaked in *hyperkalemia*
length is non specific
QT interval - answerrepresents total ventricular activity from ventricular depolarization to
repolarization.
measured from the start of the qrs complex to the end of the t wave.
length 0.4-0.44 seconds
*should be less than half of the RR interval*
0.4-0.44 - answernormal length of qt interval?
u - answer___wave is seldom seen.
it represents the repolarization of the Purjinkie fibers
*indicates hypokalemia*
it is part of ventricular repolarization
sinus bradycardia - answerwhat rhythm is this?
Rate is less than 60
rhythm is regular
P wave is present
QRS is 0.04-0.12-normal
PR is 0.12-0.2 normal
causes: meds-BETA BLOCKERS, digoxin, narcotics, athletes.
S/S: dizzy, tired, syncope, orthostatic hypotension
TX: take time to change positions, drink caffiene, pace maker, increase fluids,
decrease/DC meds
for a SYMPTOMATIC patient: give atropine
sinus tachycardia - answerwhat rhythm is this?
