Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Coronary Sinus Branch Pacing
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
Biotronik Vision Guidewire
The apical, mid ventricular and basal sites within the anterior,posterior and lateral coronary sinus branch veins will be paced.
