Methodology · worked example, guidelines & full notes
Anticoagulation continues at least 4 weeks after cardioversion regardless of duration or stroke risk, because of thrombus risk during atrial stunning. (original synthesis · not guideline verbatim)
When to use
Use to decide pre-cardioversion anticoagulation (or TEE) and the mandatory post-cardioversion course, separating unstable patients who need immediate cardioversion.
How it works
Unstable → immediate cardioversion, anticoagulate ASAP. Definite < 24 h → early cardioversion possible without 3 weeks of anticoagulation (2024 ESC/EACTS). ≥ 24 h/uncertain → anticoagulate ≥ 3 weeks or TEE-exclude thrombus. All → ≥ 4 weeks after cardioversion.
Key points
- Anticoagulation continues at least 4 weeks after cardioversion regardless of duration or stroke risk, because of thrombus risk during atrial stunning. (original synthesis · not guideline verbatim)
- Long-term anticoagulation is decided by CHA₂DS₂-VASc, not by whether sinus rhythm was achieved.
- A left-atrial-appendage thrombus on TEE defers cardioversion for 4–12 weeks of anticoagulation.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

|---|---|
| Hemodynamically unstable | No |
→Pre-cardioversion anticoagulation strategyDefinite < 24 h: early cardioversion possible
- Peri-cardioversion：Definite duration < 24 h: early cardioversion without 3 weeks of prior anticoagulation is possible (2024 ESC/EACTS; PMC11666470 commentary). Continue anticoagulation at least 4 weeks after cardioversion
- After cardioversion：Regardless of sinus-rhythm maintenance or stroke risk, anticoagulate at least 4 weeks after cardioversion (thrombus risk during atrial stunning)
- Long-term anticoagulation：Whether to anticoagulate long-term is decided by CHA₂DS₂-VASc stroke risk (see AF anticoagulation tool), not by whether cardioversion was done or sinus rhythm achieved
| AF duration | ≥ 24 hours or uncertain duration |
|---|---|
| Hemodynamically unstable | Yes |
→StrategyImmediate cardioversion (no delay)
- Cardioversion：Hemodynamically unstable (hypotension/myocardial ischemia/acute HF/shock): immediate synchronized cardioversion, not delayed for anticoagulation
- Anticoagulation：Start anticoagulation as soon as possible (UFH/LMWH or NOAC); continue at least 4 weeks after cardioversion
- Long-term：Then decide long-term anticoagulation by CHA₂DS₂-VASc (see AF anticoagulation tool)
