Flashcards in Pacemakers Deck (13):
0
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
