Pre-Hospital Interventions: Atrial-Fibrillation with RVR

🚑 Do you know the impact of prehospital interventions on patients with Atrial Fibrillation with Rapid Ventricular Response (AF-RVR)?

📊 Study Insights:

- Data: 2021 ESO Data Collaborative for 911 responses.

- Included: 4859 Patients with AFib with RVR (heart rate ≥ 110 bpm) matched to 4859 similar untreated patients.

- Interventions: Calcium channel blockers (e.g. Diltiazem), beta-blockers, or cardioversion.

📈 Results:

- Treated patients had better prehospital rate control (41% vs. 18.2% in untreated).

- Higher discharge from ED in the treated group (37.9% vs. 34%).

- Lower mortality for treated patients (4.3% vs. 6.7%).

- Hypotension was more common in treated but primarily transient.

Adverse Events: Focused on bradycardia, hypotension, and cardiac arrest during prehospital care.

🔍 Method:

- Retrospective study with propensity score matching to reduce bias.

💡 Conclusion:

- Prehospital ALS improves rate control, ED discharge rates, and lowers mortality in AF-RVR.

- Highlights need for further research.
