A more detailed discussion of pacemaker technology is conducted elsewhere. Specifically, single and dual chamber pacing modes have their own dedicated chapter.
Previous questions about pacing modes include:
This is a brief point-form summary.
Single chamber pacing modes
Dual chamber pacing modes
Position 1: chamber paced |
Position 2: chamber sensed |
Position 3: response to sensing |
O = none |
O = none |
O = none |
A = atrium |
A = atrium |
T = triggered |
V = ventricle |
V = ventricle |
I = inhibited |
D = dual |
D = dual |
D = dual (triggered and inhibited) |
Pacing Mode | Description | Advantages | Disadvantages |
AOO | asynchronous atrial pacing. |
|
|
AAI | atrial demand pacing |
|
Increased risk of perforating the thin atrial wall |
AAT | atrial pacing |
|
|
VOO | asynchronous ventricular pacing |
|
|
VVI | ventricular demand pacing |
|
|
VVT | ventricular pacing |
|
|
VAT | atrial sensing, ventricular pacing |
|
|
DDD | dual chamber demand pacing |
