Pacemakers

Question 0

What is the power source of a pacemaker?

Answer 0

Battery unity called a pulse generator

Question 1

What are the three components of a pacemaker?

Answer 1

Power source
Conducting wire
Return wire

Question 2

What is a conducting wire of a pacemaker?

Answer 2

Electrode that goes to the heart to provide stimulus

Question 3

What is the return wire of a pacemaker?

Answer 3

Wire that returns to the battery unit to complete electrical circuit

Question 4

What are AV synchronous pacemakers?

Answer 4

Pacemakers that stimulate both the atria and ventricles in sequence

Question 5

What are single chamber pacemakers?

Answer 5

Pacemaker that stimulate either the ventricles or the atria

Question 6

What are dual chamber pacemakers?

Answer 6

Pacemaker that stimulates both atria and ventricles

Question 7

What are two ways pacemakers initiate impulses?

Answer 7

Triggered

Inhibited

Question 8

How do triggered pacemakers initiate impulses?

Answer 8

Fire impulses according to a predetermined plan regardless of patients underlying cardiac activity

Question 9

What are two single chamber pacemakers?

Answer 9

Ventricular Demand Pacemaker (VVI)

Atrial Demand Pacemaker (AAI)

Question 10

What do atrial demand pacemakers (AAI) do?

Answer 10

Senses and paces the atria

Question 11

What does O mean recharging sensed chambers for pacemakers?

Answer 11

Neither atria nor ventricle were sensed

Question 12

What do AV synchronous pacemakers (VDD) do?

Answer 12

Senses atrial and ventricular activity but paces only the ventricle
