Key result
The frequency of premature atrial complexes and supraventricular tachycardia episodes in the 24 hours after electrical cardioversion did not predict atrial fibrillation recurrence at 6 months (P=0.60).
Why the study?
Does the frequency of supraventricular ectopy or SVT after electrical cardioversion predict recurrence of AF in patients with persistent AF?
Population
44 patients with documented persistent atrial fibrillation who underwent external direct current cardioversion
Design
Cohort
Follow-up
6 months

Post-cardioversion ectopy frequency does not predict AF recurrence; leaves open identification of reliable early markers in persistent AF.
Observational (n=44)
Does the frequency of supraventricular ectopy or SVT after electrical cardioversion predict recurrence of AF in patients with persistent AF?
p-value: p=0.60
The frequency of supraventricular ectopy or SVT runs in the 24 hours after electrical cardioversion does not strongly predict AF recurrence at 6 months.
Chong et al. (2006) conducted an observational in Persistent atrial fibrillation (n=44). Frequency of supraventricular ectopy (PACs and SVT) was evaluated on Recurrence of atrial fibrillation (p=0.60). The frequency of premature atrial complexes and supraventricular tachycardia episodes in the 24 hours after electrical cardioversion did not predict atrial fibrillation recurrence at 6 months (P=0.60).
