Normal + Abnormal Measurements Flashcards
PR interval
0.12 - 0.20
3-5 small squares
QRS
</= 0.10
2.5 squares or smaller
long PR
AV block Type 1
wide QRS
BBB, ventricular tachy, PVC
all P’s are different size and shapes
WAP
wandering atrial pacemaker
P is small and abnormal, usually pointy
PAC
premature atrial contraction
P right next to T with no QRS
NONCONDUCTED PAC
T + P combine
norm rhythm: PAT
140-250: Atrial Tach
PAT vs A. Flutter?
Flutter has 0 isoteric lines
A flutter atrial rate
250-400
A fib atrial rate
400 or more
Atrial tach atrial rate
140-250
inverted P wave
PJC
premature junctional contraction
HR calculation
1500/ number of squares bw 2 R
Sinus BLOCK vs ARREST
BLOCK: R-R returns on time
ARREST: doesn’t return on time
Idioventricular Rhythm
wide QRS
30-40 beats
