Outcome Measures
Primary Outcomes (1)
QRS Frequency at Each Paced Location
Time frequency analysis performed at each location
Baseline
Study Arms (1)
Coronary Sinus Branch Pacing
EXPERIMENTALAfter 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
Interventions
The apical, mid ventricular and basal sites within the anterior,posterior and lateral coronary sinus branch veins will be paced.
