Palpitations Flashcards
ECG leads/artery
anterior?
posterior?
Inferior?
lateral?
determine axis how?
Sinus tachycardia
treat cause
rate?
distinguished how? cause?
Multifocal Atrial Tachycardia
greater than 100/min
P waves varying shapes b/c 3 or more atrial foci incolved.
each paces own rate but combined above 100
whats missing?
anything regular?
in healthy young people?
A fib
caused by?
what occurs at node?
p wave?
Premature atrial contraction
irritable focus fires spontaneously
premature atrial depol not SA node
P wave
resetting of SA node occurs
what is it
why only some QRS?
A flutter
irritable atrial automaticity focus
AV node refrac makes it so only some will cause a QRS vventricle depol
saw tooth
inlcludes?
resembles?
feature?
treat
SVT supraventricular tachycardia\
includes PAT PJT
resemble rapid PVCs
QRS narrow
give adenosine
AV Nodal Reentry Tachycardia
circuit paces atria and ventricles
can be caused by?
identifiers?
Premature ventricular contraction
PVC
opoosite polarity normal QRS
pause after PVC
MVP can cause
may signify what?
V TAc
coronary insufficiency
caused by?
Torsades de pointes
low K, meds that block K channels, congenital (long QT syndrome)
Treatment?
V fib
multi ventricular foci discharging. erratic rhythm no identifiable waves
need immediate treatment
look at what leads?
LBBB
book says V5/6
but bnb say look at V1 if negatibe
should have wide QRS
RBBB
V1/2 QRS widened positive
vessel?
giveaway?
Left anterior Hemiblock
LAD MI
QRS normal/wide
Q1S3
Q in 1
s wide or deep in 3
vessel?
giveaway?
Left posterior Hemiblock
RAD MI
S1Q3
deep wide S in 1
Q in 3
Hyperkalemia
wide QRS Peaked T waves
extreme- no p wave widened QRS
Hypokalemia
moderate- falte T wave U wave
Extreme- prominent U wave
what will you see in PE?
WPW
shortned PR and lengthened QRS
