Classification-atrial fibrillation

參考➡️ Reassessment of risk for stroke during follow-up of patients with atrial fibrillation

Paroxysmal

• Terminates spontaneously or with intervention within 7 days of onset.
• Episodes may recur with variable frequency.
• Paroxysmal (terminates spontaneously or within 7 d) vs. persistent (>7 d) vs. long-standing persistent (>1 y) vs. permanent (no plan for SR)

Persistent

• Continuous sustained >7 days

Long-standing persistent

• Continuous >12 mo in duration.

Permanent

• Used when the patient and clinician make a joint decision to stop further attempts to restore and/or maintain sinus rhythm.
• Acceptance represents a therapeutic attitude on the part of the patient and clinician rather than an inherent pathophysiological attribute.
• May change as symptoms, efficacy of therapeutic interventions, and patient and clinician preferences evolve.

Nonvalvular

• In the absence of rheumatic mitral stenosis, a mechanical or bioprosthetic heart valve, or mitral valve repair.
• Nonvalvular vs. valvular (mechanical heart valve or moderate-severe MS)

With Rapid Ventricular Response (RVR)

• With persistent ventricular heart rate >100 beats per minute
