Parasympathetic nervous system

Question 5

What is refractoriness?

Answer 5

The time the cells need after they discharge before they can react to another stimulus

Question 6

Sits right at atrium and travels to AV node by means of intranodal pathway?

Answer 6

Sinoatrial Node

Question 7

Group of cells that help the impulse travel from right atrium to left atrium?

Answer 7

Bachman bundle

Question 8

Sits in lower section of right atrium. Allows a pause so the atria can depolarize and empty before the ventricle contracts.

Answer 8

Atrioventricular node

Question 9

Answer 9

His - Purkinje system

Question 10

Question 16

QT interval

Answer 16

0.36-0.44 seconds

Question 17

What is a sinus pause?

Question 20

What is oversensing?

Answer 20

Too sensitive, recognizes artifact or interference. Does not fire when it should and the patient isn’t getting enough.

Question 21

VADTIO 123

Answer 21

V = ventricle
A = atrium
D = dual
T = triggered pacing
I = inhibit pacing
O = not applicable

1 = chamber being paced
2 = chamber being sensed
3 = response to sensed event
