Pacemakers (know indications for)
Pacing code (NBG, positions I-V)
| I Paced | II Sensed | III Response | IV Rate | V Multisite |
|---|---|---|---|---|
| A / V / D / O | A / V / D / O | Trigger / Inhibit / Dual / O | R = rate response | A / V / D |
- DDDR - dual chamber, rate responsive. Default for sinus node disease or AV block in sinus rhythm
- VVIR - single ventricular lead. Permanent AF with slow ventricular response
- AAI - atrial only; rarely used - AV block develops in ~1-2%/yr
- DDI / DDDR with mode switch - avoids tracking atrial tachyarrhythmia
- VOO/DOO (asynchronous) - magnet mode, used intra-operatively with diathermy
