Left vs Left Randomized Clinical Trial

Plain-language summary
The investigators aim to prospectively test the comparative effectiveness of His or Left bundle branch pacing in relation to patient centered outcomes (quality of life, physical activity, heart failure hospitalization, mortality) and comparative safety in relation to device-related complications and re-interventions (e.g., lead dislodgement, infection) relative to standard of care biventricular pacing in patients with heart failure due to left ventricular systolic dysfunction (LVEF≤50%) and with either a wide QRS (≥130 ms) or with/anticipated \>40% pacing who are already receiving current standard heart failure pharmacological therapy.

* A LVEF ≤ 50% within 6 months prior to enrollment.
* Resting QRS duration ≥130 ms as evidenced by a historical 12-lead ECG prior to enrollment OR anticipated right ventricular pacing \>40% OR device in place with right ventricular pacing \> 40%.
* Are optimized on HF guideline directed medical therapy according to current HF published guidelines OR patient's physician will make an effort to start all guideline-directed medical therapy and titrate doses up as permitted by the participant clinical status and co-morbidities prior to implantation procedure.
Exclusion Criteria:
