32
Q

A

33
Q

every QRS complex is preceded by a P wave and every P wave must be followed by a QRS is called

A

normal sinus rhythm

34
Q

What is a normal sinus rhythm

A

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
Q

rate of more than 100 bpm in a normal adult but often it is limited below 150 bpm

A

Sinus Tachycardia

36
Q

Every QRS complex is preceded by a P sinus wave and every P wave must be followed by a QRS

A

Sinus Tachycardia

37
Q

What is Sinus Tachycardia

A

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
Q

What rhythm does not give the heart time to relax

A

sinus tachycardia

39
Q

rate of less than 60 bpm in a normal adult

A

sinus bradycardia

40
Q

what type of sinus rhythm may constant in athletes

A

sinus bradycardia

41
Q

what rhythms must have a QRS complex preceded by a P Wave and must be followed by a QRS

A

normal sinus rhythm, sinus tachycardia, and sinus bradycardia

42
Q

this rhythm is irregular, with the rate increasing on inspiration and decreasing on expiration

A

sinus arrhythmia

43
Q

A difficult rhythm, often it is benign

A

sinus arrhythmia

44
Q

this commonly seen in children and less common in adults

A

sinus arrhythmia

45
Q

What is a sinus exit block/sinoatrial block?

A

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
Q

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

a sinus exit block or sinoatrial block

47
Q

occurs when there is a premature firing from the SA node.

A

Premature Atrial Contraction

48
Q

PAC

A

Premature Atrial Contraction

49
Q

Why does a PAC occur when there is a premature firing from the SA node.

A

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
Q

When the P wave and the T wave combine

A

Premature Atrial Contraction

51
Q

When the P wave come before the dissolution of the T wave.

A

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
Q

Is one event, not a rhythm

A

Premature Atrial Contraction

53
Q

rapid, disorganized electrical signals cause the atria to fibrillate

A

A-Fib

54
Q

means to contract very fast and irregulalry

A

fibrillate

55
Q

What does A-Fib occur

A

AF occurs if rapid, disorganized electrical signals cause the atria to fibrillate.

56
Q

the heart’s two upper chambers are called

A

the atria

57
Q

A sick SA node is an indication of

A

A-Fib

58
Q

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

A-Fib

59
Q

The heart’s lower chambers

A

ventricles

60
Q

one of the most common arrhythmias that is seen in clinical practice. It is particularly prevalent in the elderly population.

A

Atrial Fibrillation

61
Q

When the AV node is bombarded by a barrage of imposes and cannot conduct all of them to the ventricles… what is this call

A

Atrial Fibrillation thankfully conduction to the ventricles is variable and can range from bradycardia to tachycardia.

62
Q

What is fast or uncontrolled atrial fibrillation.

A

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
Q

What is controlled A-Fib

A

A ventricular rate of less than 100 is generally referred to as controlled Atrial fibrillation

64
Q

Atrial Fibrillation may be seen as a consequence of the following

A

-Advanced age, Atrial enlargement, alcohol, myocardial infarction, heart failure, pulmonary embolism, pericarditis, idiopathic

65
Q

Term for not knowing the cause of a disease

A

idiopathic

66
Q

infection of the heart

A

pericarditis

67
Q

blood clot

A

pulmonary embolism

68
Q

diseased atrial

A

Atrial Fibrillation

69
Q

When looking on a EKG or ECG for Atrial Fibrillation what characteristics would you see

A
  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
Q

squiggly lines on A-Fib strip

A

fibrillatory wave or F wave

71
Q

the results from an reentry circuit within the atria at a rate of 250-350.

A

Atrial Flutter

72
Q

this dysrhythmia is recognized by the sawtooth appearance of baseline

A

Atrial Flutter

73
Q

Define atrial flutter and it’s appearance

A

results from an reentry circuit within the atria at a rate of 250350. This dysrhythmia is recognized by the sawtooth appearance of the baseline
