Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time to First Atrial Fibrillation (AF) Recurrence or Atrial Flutter Emergence Defined by the Time to First Episode of AF or Atrial Flutter Lasting for at Least 10 Minutes During the 20-week Follow-up After Visit 3 (Electrical Cardioversion (ECV) Visit).
Time Frame: from electrical cardioversion (Visit 3) to last follow-up visit (W24)
Time to first Atrial Fibrillation (AF) recurrence defined by the first episode of Atrial Fibrillation lasting for at least 10 minutes. AF recurrences or atrial flutter emergences: 7-day continuous electrocardiogram (ECG; 5-leads/2 or 3 channels) ambulatory recording (Holter ECG) between Visit 3 (Electrical Cardioversion Visit) and Visit 4 (Week 5). Then, the follow-up was documented using the Transtelephonic ECG monitor (TTEM): one transmission every two days from Week 9 to Week 24. For randomised patients with spontaneous cardioversion before Electrical Cardioversion, the recurrence of AF or the emergence of atrial flutter was assessed after Visit 3 (from Week 5). Moreover, during this TTEM period, if the patient experienced any AF or atrial flutter symptoms, it was recorded and documented using the TTEM.
from electrical cardioversion (Visit 3) to last follow-up visit (W24)
