Please assess the completion status of the following clinical trial:

Trial Title: Dual Chamber Versus Single Chamber Cardiac Pacing in People 80 Years of Age and Older

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:~* 80 years of age and older~* Symptomatic bradycardia~Exclusion Criteria:~* Permanent atrial fibrillation~* Previous pacemaker implant~* Life expectancy less than 1 year~* Geographic isolation~* Unable to give informed consent

- Gender: ALL
- Minimum Age: 80 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- 1 (Type: OTHER): Physiologic pacemakers usually have two leads - one positioned in the right atrium (upper heart chamber) and one positioned in the right ventricle.
- 2 (Type: OTHER): Ventricular pacemakers have a single lead (wire) positioned in the right ventricle (lower pumping chamber) to sense and pace the ventricle.

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