QRS wave
Q wave is any downward deflection immediately following the P wave.
R wave follows as an upward deflection, and the
S wave is any downward deflection after the R wave.
Normal P wave /PR c program languageperiod
amplitude: <2.5mm
period: <0.12 seconds
PR interval: 0.12-0.20 seconds
, QRS complex width
0.06-0.11 seconds
12 ekg paper (inferior, lateral, anterior, septal) which one do you ignore
how to determine rates
• 6-second method
• 300, 150, 100, 75, 60, 50
• Precise: 1500 / # small boxes R to R
normal
bradycardia
tachycardia
normal: 60-100
bradycardia: 40-60
tachycardia: 100-160
Sinus Exit Block
pause when impulse not conducted out of SA node; pause is exactly 2 R-R intervals
Sinus Arrest
NO P WAVE (where as non con PAC does)
o Pause greater than or equal 1.6 seconds (40 small box)- Basic rhythm does not resume on
time
Wandering Atrial Pacemaker
P waves-Vary in size, shape, and duration across the rhythm strip- One P wave precedes each
QRS
Multifocal atrial tachycardia
>100bpm ordinary or irregular (Faster WAP)
