ECG Made Easy 4 Flashcards
frist Rx for any abnormal tachycardia?
carotid sinus pressure
narrow complex tachys should be treated how?
adenosine
wide complex tachys should be treated how?
lidocaine
what causes P waves to become peaked?
right atrium hypertrophy
what causes a bifid P wave?
left atrial hypertrophy
wide QRS cause?
BBB
ventricular focus
what does QRS look like in wolfe-parkinson-whyte?
wide
where to see right ventricle? looks like in hypertrophy?
V1: QRS becomes upright (always abnormal)
all the ways that the P wave present?
Normal
too broad
too tall
all the ways that the QRS present
Too tall
too broad
abnormal Q wave
all the ways that the T wave can present?
upright
wrong way up
all the ways that the ST segment can present?
normal
elevated
depressed
P wave too tall means?
Right atrial hypertrophy
what cases bifid P-wave?
Left atrial hypertrophy
2 causes of wide QRS?
bundle branch block
Wolff-Parkinson-White
if V1 QRS become upright means what?
right ventricular hypertrophy, always abonormal
3 things for wolfe-parkinson-white?
delta plus
wide QRS
Narrow PR
SVT with wolfe parkinson white, how does QRS look like?
narrow due to re-entry pathway. looks like regular SVT, can’t tell difference
how to reverse SVT? med?
adenosine
Then 12 lead ECG to check for WPW
Atrial fibrillation with WPW can look like?
Wide QRSs &
narrow QRSs
If negative in Lead II means?
left axis deviation
if negative in Lead I means what?
right axis deviation
sinus arrythmia happens when?
during breathing
inspiration faster
expiration slower
a Q wave is only significant when what?
in multiple leads: like V1,2,3 or V2,3,4
first thing to think of with tachycardia and wide QRS?
Ventricular tachycardia
can walk in and look well
