Atrial Dysrhythmia

Question 1

What causes atrial dysrhythmia?

Answer 1

An ectopic impulse in atrium that overides SA node occurs from conditions that causes pressure in atria

Question 2

Define ectopic beat

Answer 2

myocardial cell that generates electricity that overides SA node (PAC/PVC)

Question 3

What would a normal rhythm be called when there is a premature atrial contraction present? What is the morphology of the PAC?

Answer 3

rhythm: regular with PAC

early complex pwave : early beat may be flattened or unusual

Question 4

What does PAC stand for?

Answer 4

Premature atrial contractions

Question 5

What are some PAC symptoms?

Answer 5

low cardiac output frequency is related to severity of patient’s complaints frequency may indicate flutter

Question 6

Define trigeminy.

Answer 6

pattern in which every third complex is a premature beat

Question 7

Define bigeminy

Answer 7

every second complex is a premature beat

Question 8

What is WAP?

Answer 8

pacemaker shift between SA node, atria and AV junction

P wave configuration changes in appearance

Question 9

What is uniquely in WAP?

Answer 9

p wave configuration with at least 3 variations in one lead

Question 10

What rhythm is MAT frequently mistaken as?

Answer 10

Atrial fibrillation

Question 11

Flutter

Answer 11

is the cutter

ectopic focus may originate from ischemic areas causes a loop myocardium

can happen in atria or in ventricle

Question 12

Name 3 symptoms to low cardiac output

Answer 12

1. fatigue
2. dizzy
3. pale

Question 13

Describe atrial fibrillation

Answer 13

1. multiple atrial activity recorded as chaotic wave
2. R-R is irregular
3. PR interval cannot be identified
4. described as quivering
5. lead to stroke if not on blood thinners

Question 14

What is a major health risk for patients with a fib?

Answer 14

Thrombus formation and embolism due to blood collecting in atria

Question 15

syncope

Answer 15

passing through
