26
Junctional Rhythm Retrograde HR
Slow 40-60 bpm
27
junctional Rhythm Retrograde p-wave
Present + inverted OR not present
28
Junctional Rhythm Retrograde P:R ratio & P:R Interval
yes 1:1 if p wave is inverted & present if p-wave is inverted and present 0.12-0.20 seconds
29
Accelerated Junction Rhythm hr
60-100 bpm
30
Accelerated Junctional Rhythm Rhythm
REGULAR
31
What is the key difference between accelerated Junctional rhythm and junctional rhythm Retrograde?
the heart rate
32
What dictates the heart rate and rhythm for PVCs?
the underlying rhythm
33
Is the p-wave present, is there p:R ratio and p:R Interval for PVC
not present no 1:1 N/A abnormal
34
How do you categorize the QRS complex for a PVC?
weird, wide and bizarre
35
define multifocal PVC
PVC looks different
36
Ventricular Bigeminy
normal beat & PVC every other
37
Ventricular Trigeminy:
2 normal beats and PVC
38
Ventricular Quadrigeminy:
3 normal beats and a PVC
39
How long does a run of V Tach have to be to be considered one?
6 or more
40
Ventricular Couplet
2 V Tach (unifocal PVCS)
41
What dictates HR and rhythm for Premature Atrial Contraction
varies depending on underlying rhythm
42
Characteristics of PAC
PAC P wave will always look weird SA node sends a premature signal Irregularly sent
43
How do you find the rhythm and heart rate of a ventricular Bigeminy?
You can't because there not at least 3 rhythms in a row
44
How do you name a ventriuclar Bigeminy?
You just call it a ventricular Bigeminy since you can't find the rhythm
45
How would you name a rhythm with two beats before a run of V Tach
2 beats before a run of # V Tach
46
What is the P:R Interval for First Degree AV Block
Always Prolonged >0.20 seconds Abnormal
47
If your QRS is far from your P, then you have
1st degree
48
What rhythm does Second Degree AV Block Type 1 have? What does it mean?
Regularly Irregular Irregular beat after a certain pattern
49
Is there a P:R ratio for Second Degree AV Block Type 1
Not 1:1 abnormal
50
P:R interval for 2nd degree AV Block Type 1
Progressively lengthening of the PR interval until QRS complex is dopped
51
What is the cause of AV (atrioventricular blocks)
AV Nodal disease
52
Longer, longer, longer, drop makes the rhythm
Wenckebach (Second Degree AV Block Type 1/ Mobitz 1)
53
2 causes of SVT
1)stress 2) problem with electrical pathway
54
treatment for SVT
Ablation; burn heart tissue so electrical pathways reset
55
SInus Tachycardia 4 causes
1. unhealthy 2 excercise 3. caffeiene 4. anxiety & stress 5. sickness
56
PAC symptom
may feel a beat little early
57
Rhythm for Second Degree AV Block Type 2 (Mobitz 2)
irregular
58
P:R ratio for Second Degree AV block Type 2 (Mobitz 2)
Not 1:1 periodically missing QRS
59
PR interval, QR complex, and QT Interval for Second Degree AV block Type 2 (Mobitz 2)
Normal when the beat is present 0.12-0.20 sec Normal when present 0.04-0.12 seconds Normal when present <0.44 seconds
60
If some p-waves don’t go through you have
Mobitz 2
61
HR for Third Degree AV block (Complete Heart Block)
< 60 bpm
62
P wave for Third Degree AV block (Complete Heart Block)
Present & Upright Unrelated
63
P: R ratio Third Degree AV block (Complete Heart Block)
1:1 no
64
P:R interval & QRS complex Third Degree AV block (Complete Heart Block)
N/A abnormal
65
When ps and qs just don’t agree ,then you have
3rd degree
66
QRS complex for Bundle Branch Block
>0.12 seconds Abnormal Prolonged & wide
67
QT Interval for Bundle Branch Block
Abnormal & can’t measure
68
Causes of BBB
When there’s a delay in the two ventricles receiving the signal
69
What can BBB also look like
rabbit ears
70
Which side of the heart of BBB is dangerous
left
71
Atrial Fibrillation HR
100-160 bpm
72
Rhythm of A FIb
Irregular
73
P-wave of A FIb
Not present & atria is fibrillating
74
PR ratio of A fib
Not 1:1
75
PR interval for A FIb
N/A abnormal
76
Causes of A Fib
1.Apnea 2. High blood pressure
77
Treatment for A Fib when stroke
Blood thinners
78
How can a stroke occur bc of A fib?
Blood clot forms in atria, which gets pumped to ventricles and into the brain
79
HR of Atrial Flutter
100-150 bpm
80
rhythm of Atrial Flutter
regular
81
