Implication

Limited sinus rhythm maintenance after cardioversion warrants clinical caution; leaves open refined selection for flutter and short-duration AF.

Key Points

To evaluate the safety, immediate efficacy, and long-term persistence of normal sinus rhythm following electrical conversion in patients with atrial flutter and atrial fibrillation.
Conducted a follow-up investigation of 50 patients who underwent electrical conversion for atrial flutter or atrial fibrillation.
Monitored patients across a mean follow-up duration of ten months to determine sinus rhythm retention rates.
Normal sinus rhythm persisted in only 42% of patients whose arrhythmias were successfully converted initially over a mean follow-up of ten months.
Immediate and long-term outcomes were markedly superior in patients with atrial flutter compared to those with atrial fibrillation.
Patients with atrial fibrillation duration of less than two years experienced significantly better rhythm maintenance than those with longer-standing arrhythmia.

Structured PICO

Does electrical conversion maintain long-term normal sinus rhythm in patients with atrial flutter and atrial fibrillation?

Population

50 patients with atrial flutter or atrial fibrillation whose arrhythmias were initially converted to normal sinus rhythm

Intervention

Electrical conversion (electroshock)

Outcome

Persistence of sinus rhythmsurrogate

While electrical conversion of atrial flutter and fibrillation is initially effective, long-term maintenance of sinus rhythm is limited (42% at 10 months), though outcomes are better for atrial flutter and shorter-duration atrial fibrillation.
