Pacemaker Reference Card | NBG Code, Pacing Modes, Malfunctions

"Is it failure to capture or failure to sense?" This 2-page Pacemaker reference card answers that at a glance — because every malfunction is drawn on a calibrated rhythm strip with visible blue pacing spikes, not just described in text.

WHAT'S INSIDE (2 pages):

Side 1 — FUNCTION:
- How pacing works: pace, sense, inhibit, trigger — in plain language
- System & key parameters: LRL/URL, AV delay, PVARP
- The NBG 5-letter code, decoded letter by letter
- Pacing modes table: VVI(R), AAI(R), DDD(R), VOO/DOO — what each does and when it's used
- DDD's four pacing states (AsVs, AsVp, ApVs, ApVp) and when you see each
- Choosing the mode by situation
- Recognizing the paced rhythm on paper

Side 2 — MALFUNCTIONS (all drawn on strips):
- Failure to capture: spike with no beat
- Failure to sense (undersensing): spikes marching through native beats
- Oversensing / failure to pace: pauses where a spike should be
- Pacer-dependent emergencies and magnet behavior
- Transcutaneous pacing bridge
- ICD & CRT basics in brief

PERFECT FOR: Telemetry, ICU/CCU, and ED nurses, EP lab staff, paramedics, nursing and NP/PA students, CCRN candidates.
