Q

look at leads I and avF to assess

A

QRS for Mean axis

lead I: left hand
lead avF: right hand

25
P wave is tall in lead II | and tall upright QRS wave in V1
RAE | "P pulmonale"
26
P wave is wide or notched in lead II | and exaggerated negative QRS wave in V1
LAE | "P mitrale"
27
Atria tend to
dilate
28
Ventricles tend to
hypertrophy
29
One big box
200 ms
30
Normal P wave
60-100 ms | up to HALF of a big box
31
leads II and V1
P waves
32
1st part of P wave is big in V1
RAE
33
2nd part of P wave is big in V1
LAE
34
leads I and avF
Mean axis
35
left thumbs up correlates with ____ when determining Mean axis
Lead I
36
right thumbs up correlates with ___ when determining Mean axis
Lead avF
37
What often co-occurs with Right Ventricular Hypertrophy, RVH?
RAD, Right axis deviation So, after looking at V1, and V6, look at leads I and avF to see if the Mean axis shows RAD
38
Which is the more common Ventricular hypertrophy?
LVH!
39
LVH criteria, where to look?
V1-V2 and V5-V6 AND R wave in avL
40
LVH criteria
Deepest wave in V1-V2 + tallest in V5=V6 >35 R in avL >11 (meaning super DEEP)
41
What to notice in LVH
avL has DEEP wave Super DEEP waves in V1-V2 Super TALL waves in V5-V6
42
RVH criteria
RAD presence V1: R > S wave (first tall part > last deep part) V6: S > R wave R wave is like going "down the stairs" from V1-V4
43
Sinus arrest
THREE or more beats dropped
44
Sinus PAUSE
not as intense 1-2 beats dropped
45
Wandering atrial pacemaker
Pacemaker site shifts from SA, atria, and AV jx P waves change in appearance (3 or more) RATE is usually normal
46
PAC premature atrial complex
Most P waves are normal other than the one preceding the PAC, this one has a different morphology
47
PAC are followed by
Non-compensatory pause
48
Sinus tachy
100-160 bpm | P waves are normal and easily seen
49
Atrial tachy
150-250 bpm | much faster than Sinus tachy
50
Are P waves easier seen in Sinus tachy or Atrial tachy?
Sinus tachy bc this beat is slower (100-150) In Atrial tachy, the beat is so fast (150-250) that P waves can be upright, inverted, or HIDDEN
51
Multifocal Atrial Tachycardia
120-150 and CHANGING P WAVE morphology May be confused w A-fib
52
Rate 120-150 with changing P wave morphology
Multifocal Atrial Tachycardia
53
Atrial Flutter
Lots of flutter waves in between QRS complexes
54
Atrial flutter
Atrial rate is 250-350 | Ventricular rate can still be normal
55
Saw tooth appearance
Atrial FLUTTER
56
Main characteristic of Supraventricular Tachycardia
P waves CANNOT be seen (dont know if its coming from atria or junctional, we just know its above the ventricles) Rate example: 180
57
A-Fib, Atrial rate is SO FAST
>350 | tons of crazy looking chaotic energy between QRS complexes
58
Baseline fibrillatory waves (f waves)
A-Fib
59
Flutter waves (capitol F)
A-Flutter
