Please assess the completion status of the following clinical trial:

Trial Title: Survey of QRS Frequency at Various Left Ventricular Pacing Sites for Cardiac Resynchronization

Study Design Characteristics:
- Allocation: None
- Intervention Model: SINGLE_GROUP
- Observational Model: None
- Primary Purpose: BASIC_SCIENCE
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 1.0

Eligibility Criteria:
Inclusion Criteria:~* Standard implantation for cardiac resynchronization ICD or PM implantation~* Cardiomyopathy with LVEF \<35%~* QRS duration greater than 120 msec~Exclusion Criteria:~- Age less than 18 years

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

Study Arms:
- Coronary Sinus Branch Pacing (Type: EXPERIMENTAL): After cannulation, pacing impulses will be delivered via a Biotronik Vision Guidewire to 3 sites (apical, mid ventricular, and basal) within each coronary sinus branch receiving venous blood from the anterior, lateral and posterior regions of the ventricle.~ECG signals will be saved digitally for analysis

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