EKG
100
Upright and rounded, SA node fires
P WAVE
100
AV NODE intrinsic rate
40-60
100
1 small block on EKG PAPER
0.04 sec ( time)
100
Rate less than 60, can be caused by drugs, digoxin, BB, CCB
100
Or interval greater than 0.12 or 3 sm blocks
Heart block
100
Atrial Flutter
F waves
200
Atrial depolarization or contraction
PR interval
200
First downward deflection on EKG
what is Q wave?
200
# small boxes in 1 large square
5, 5 large boxes = 1 second, 30 big boxes = 6 seconds
200
Rate greater than 100 less than 160
Sinus tachycardia
200
Cardioversion
Synchrononized with R wave, treat AF AND A Flutter
Anticoagulant before and after at least for 1 month prevent stroke, sedate pt
200
atrial fibrillation
300
Normal PR INTERVAL
0.12 (3 small blocks) -0.20 ( 5 small blocks)
300
First upward or positive deflection after Q wave
R wave
300
How to count rate in six second strip
Count the # R waves and multiply by 10. Ex. 14 R WAVES X 10= 140 bpm for HR
300
Can be due to stress, hypoxia, hypokalemia, excess caffeine, alcohol,
Vagal maneuvers, BB, ablation
SVT Supra ventricular tachycardia rate greater than 160, narrow QRS, p waves may not be visible
300
Defibrillation
Treat useless V tach or V Fib
Not syncronized with EKG wave form
300
v fib into asystole
400
Long PR INTERVAL or greater than 0.20 sec
First degree heart block or Dig toxicity
400
Negative deflection after R wave
S WAVE
400
Is rate regular or irregular
Compare distance between R WAVES are they equal?
400
NO P wave before PVC, wide QRS ( greater than 0.12) inverted t wave 3 or more VTach
PVC
400
2 consecutive PVC in a row
PVC couplet
400
PAC premature atrial contraction
500
Intrinsic rate SA node
60-100
500
Normal QRS INTERVAL
LESS THAN 0.012 secs or 3 small boxes
500
Sinus rhythm
Is there a P wave before every QRS?
500
3 or more PVC! With A pulse give drugs like Amiodorone, pulseless VT shock pt
500
PEA
Pulseless electrical activity , shows electrical activity on monitor but patient has no pulse
500
normal sinus rhythm (NSR) HR 80
