High Septal Pacing for Cardiac Resynchronization Therapy Acute Research Study

The purpose of this acute study is to perform a preliminary investigation of high septal right ventricular pacing in the vicinity of the His bundle region as an alternate or adjunctive means for cardiac resynchronization in patients with heart failure and wide QRS.
