What are the three components of a pacemaker?

Power source
Conducting wire
Return wire

1

What is the power source of a pacemaker?

Battery unity called a pulse generator

2

What is a conducting wire of a pacemaker?

Electrode that goes to the heart to provide stimulus

3

What is the return wire of a pacemaker?

Wire that returns to the battery unit to complete electrical circuit

4

What are AV synchronous pacemakers?

Pacemakers that stimulate both the atria and ventricles in sequence

5

What are single chamber pacemakers?

Pacemaker that stimulate either the ventricles or the atria

6

What are dual chamber pacemakers?

Pacemaker that stimulates both atria and ventricles

7

What are two ways pacemakers initiate impulses?

Triggered
Inhibited

8

How do triggered pacemakers initiate impulses?

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

9

What are two single chamber pacemakers?

Ventricular Demand Pacemaker (VVI)
Atrial Demand Pacemaker (AAI)

10

What do atrial demand pacemakers (AAI) do?

Senses and paces the atria

11

What does O mean recharging sensed chambers for pacemakers?

Neither atria nor ventricle were sensed

12

What do AV synchronous pacemakers (VDD) do?

Senses atrial and ventricular activity but paces only the ventricle
