Please assess the completion status of the following clinical trial:

Trial Title: Rhythm Control Versus Rate Control for New Onset Atrial Fibrillation

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: SINGLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Older than 18 years~* Newly diagnosed atrial fibrillation or flutter~* Patients with atrial fibrillation or flutter that occurred within 7 days after non-cardiac non-thoracic surgery~* Atrial fibrillation or flutter with rapid ventricular response(HR ≥110/min)~* Patients without hemodynamic instability (MBP≥65mmHg with norepinephrine continuous infusion less than 5mcg/min or without vasopressor support)~Exclusion Criteria:~* Atrial fibrillation or flutter prolonged more than 48 hours without anticoagulation~* Patients who have decreased cardiac function or heart failure (EF \<40%)~* Patients who have cardiac conduction disorder, QT prolongation(QTc ≥500ms)

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Rate control strategy group (Type: EXPERIMENTAL): Patients are given diltiazem or esmolol to control heart rate less than 110/min.
- Rhythm control strategy group (Type: EXPERIMENTAL): Patients are given amiodarone for conversion of cardiac rhythm to sinus rhythm.

Based on this trial design, predict the completion outcome and termination type (if applicable).
