Episode notes
Duration Predicts Stroke Risk
- Clinical AFib requires 30 seconds on telemetry or a 12-lead EKG to meet diagnostic criteria.
- Longer single AFib episodes predict higher stroke risk more than multiple short episodes.
ASSERT: Longer Runs, Bigger Risk
- ASSERT showed stroke risk rises with increasing longest AFib episode duration.
- Patients with any episode ≥18 hours had nearly a 5% yearly stroke or systemic embolism risk.
Sick AFib Mirrors Community AFib
- Post-op and sepsis-associated AFib (non-cardiac) behaves similarly to paroxysmal AFib in the community.
- These patients carry increased long-term AFib and stroke risk versus the general population without AFib.
