Risk Assessment
Based on the nocturnal SpO₂, perfusion index, and heart rate data, here is the risk assessment for the next 5 weeks:
Severe bradycardia (HR 28-31 bpm) combined with low perfusion index (as low as 3) indicates high risk of inadequate tissue perfusion.
Profound bradycardia can lead to cerebral hypoperfusion, resulting in syncope, especially during nocturnal hours.
While not zero, the risk of sudden death is lower than other complications. However, bradycardia can potentially trigger dangerous arrhythmias.
Clinical Implications
Nocturnal Non-Capture Issue
The data shows evidence of "nocturnal non-capture" where the leadless pacemaker is firing but failing to consistently cause heart contraction during sleep.
Recommended Actions
- Maintain close communication with cardiologist
- Monitor for symptoms of dizziness, lightheadedness, or fainting
- Ensure safe sleeping environment to prevent injury from potential falls
- Proceed with planned pacemaker upgrade to transvenous LBBAP
Expected Outcomes After Procedure
The upgrade to a transvenous LBBAP system should resolve the nocturnal non-capture issue, stabilize heart rate, and significantly reduce the risks identified above.
