ventricles are starting to relax again
The T wave
26
interval that represents the time of ventricular activity including both depolarization and repolarization.
The QT interval
27
The QT interval
the interval that represents the time of ventricular activity including both depolarization and repolarization
28
represents the early part of ventricular repolarization
The ST segment
29
The ST segment represents
the early part of ventricular repolarization
30
the line that from the end of the QRS complex to beginning of the T wave. Normally it is flat relative to the baseline.
The ST segment
31
The ST segment is the line
that from the end of the QRS complex to beginning of the T wave. Normally the ST segment is flat relative to the base line
32
rate of between 60-100 bpm
normal sinus rhythm
33
every QRS complex is preceded by a P wave and every P wave must be followed by a QRS is called
normal sinus rhythm
34
What is a normal sinus rhythm
Rate of between 60-100 bpm and every QRS complex is preceded by a P wave and every P wave must be followed by a QRS
35
rate of more than 100 bpm in a normal adult but often it is limited below 150 bpm
Sinus Tachycardia
36
Every QRS complex is preceded by a P sinus wave and every P wave must be followed by a QRS
Sinus Tachycardia
37
What is Sinus Tachycardia
A rate of more than 100 bpm in a normal adult but often it is limited to below 150 bpm and every QRS complex is preceded by a P sinus wave and every P wave must be followed by a QRS
38
What rhythm does not give the heart time to relax
sinus tachycardia
39
rate of less than 60 bpm in a normal adult
sinus bradycardia
40
what type of sinus rhythm may constant in athletes
sinus bradycardia
41
what rhythms must have a QRS complex preceded by a P Wave and must be followed by a QRS
normal sinus rhythm, sinus tachycardia, and sinus bradycardia
42
this rhythm is irregular, with the rate increasing on inspiration and decreasing on expiration
sinus arrhythmia
43
A difficult rhythm, often it is benign
sinus arrhythmia
44
this commonly seen in children and less common in adults
sinus arrhythmia
45
What is a sinus exit block/sinoatrial block?
A sinus exit block or sinoatrial block results when the impulse from the sinoatrial (SA) node is blocked and does not depolarizes the atrium.
46
Although there SA node is firing at the usual rate, the impulse are not passed on. There will be pauses equivalent to multiple P-P intervals
a sinus exit block or sinoatrial block
47
occurs when there is a premature firing from the SA node.
Premature Atrial Contraction
48
PAC
Premature Atrial Contraction
49
Why does a PAC occur when there is a premature firing from the SA node.
Premature atrial contraction occurs due to increase irritability of the atria resulting in increased automaticity. Sine the SA node firing is earlier, the complex comes earlier.
50
When the P wave and the T wave combine
Premature Atrial Contraction
51
When the P wave come before the dissolution of the T wave.
This causes the P wave to become abnormal (biphasic, raised, flattened...). A normal QRS complex (narrow QRS as it originates from the atria) flows the P wave this all occurs in a PAC.
52
Is one event, not a rhythm
Premature Atrial Contraction
53
rapid, disorganized electrical signals cause the atria to fibrillate
A-Fib
54
means to contract very fast and irregulalry
fibrillate
55
What does A-Fib occur
AF occurs if rapid, disorganized electrical signals cause the atria to fibrillate.
56
the heart's two upper chambers are called
the atria
57
A sick SA node is an indication of
A-Fib
58
When blood pools in the atria, It isn't pumped completely into the ventricles and as a result the atria and ventricles don't work together as they should.
A-Fib
59
The heart's lower chambers
ventricles
60
one of the most common arrhythmias that is seen in clinical practice. It is particularly prevalent in the elderly population.
Atrial Fibrillation
61
When the AV node is bombarded by a barrage of imposes and cannot conduct all of them to the ventricles... what is this call
Atrial Fibrillation thankfully conduction to the ventricles is variable and can range from bradycardia to tachycardia.
62
What is fast or uncontrolled atrial fibrillation.
When more than 100 atrial impulses are conducted to the ventricles this results in a ventricular rate of more than 100 beats per minute
63
What is controlled A-Fib
A ventricular rate of less than 100 is generally referred to as controlled Atrial fibrillation
64
Atrial Fibrillation may be seen as a consequence of the following
-Advanced age, Atrial enlargement, alcohol, myocardial infarction, heart failure, pulmonary embolism, pericarditis, idiopathic
65
Term for not knowing the cause of a disease
idiopathic
66
infection of the heart
pericarditis
67
blood clot
pulmonary embolism
68
diseased atrial
Atrial Fibrillation
69
When looking on a EKG or ECG for Atrial Fibrillation what characteristics would you see
1. the rhythm is irregularly irregular 2. The heart rate can be variable and depends on how many atrial impulses are transmitted from the atrial to the ventricles 3. There are no P waves 4. P waves are replaced by f waves 5. there are QRS complexes and T waves 6. P:QRS ratio is not applicable as we have no P waves 7. P-R interval is not applicable
70

71
the results from an reentry circuit within the atria at a rate of 250-350.
Atrial Flutter
72
this dysrhythmia is recognized by the sawtooth appearance of baseline
Atrial Flutter
73
Define atrial flutter and it's appearance
results from an reentry circuit within the atria at a rate of 250350. This dysrhythmia is recognized by the sawtooth appearance of the baseline
