Clinical context: Patient with nocturnal non-capture on a leadless pacemaker (LP), scheduled for transvenous LBBAP in five weeks. This page summarizes risk estimations derived from uploaded oximetry/perfusion/HR data.
Key Findings
- SpO₂ stable at 97% (no nocturnal hypoxemia detected).
- Perfusion Index (PI) variable with episodes down to 3 (low peripheral perfusion).
- Heart rate (HR) shows nocturnal bradycardia with values as low as 28–31 bpm.
Estimated Probabilities (Per Timepoint)
Avg Hypoperfusion
45.0%
Avg Syncope
35.0%
Avg Sudden Death
4.0%
These are evidence-informed estimations derived from thresholds for bradycardia and low PI. They are not deterministic predictions and should be interpreted by a clinician in context.

|---|---|---|---|---|---|---|

| 2025-09-10 03:00:00 | 97 | 30 | 8 | 30.0 | 30.0 | 5.0 |
| 2025-09-10 05:00:00 | 97 | 31 | 12 | 30.0 | 30.0 | 5.0 |
| 2025-09-10 07:00:00 | 97 | 50 | 3 | 60.0 | 30.0 | 1.0 |
Interpretation & Safety Notes
- Hypoperfusion: Moderate–high likelihood on nights with PI <5 or HR <30 bpm.
- Syncope: Moderate probability, especially with nocturnal standing or bathroom trips (orthostatic stress + bradycardia).
- Sudden death: Low but non‑zero risk; rises if HR falls <25 bpm or PI <3 persists.
- Action: Consider expedited pacing upgrade; if not feasible, use interim monitoring (Holter/telemetry), limit nocturnal orthostatic challenges, and ensure a response plan.
