Brief Summary
The LEVEL-AT Trial (LEft VEntricuLar Activation Time Shortening with Physiological Pacing vs Biventricular Resynchronization therapy: a randomized study) is a non-inferiority study that aims to determine if physiological pacing could decrease the left ventricular activation time compared with biventricular therapy.

Study Arms (2)
Physiological pacing
EXPERIMENTALPacing the his-purkinje system. Crossover to biventricular CRT will be allowed in the following situations: failed physiological pacing lead implantation; high thresholds (\>3.5V / 1ms); no shortening of QRS (shortening \<20%) or failure to meet non-selective HBP criteria \[Europace. 2019 Oct 9. doi: 10.1093/europace/euz275\].
Biventricular resynchronization therapy
ACTIVE COMPARATORPacing from the right ventricular and coronary sinus leads. Electrocardiographic optimization with fusion-optimized intervals. Crossover from biventricular CRT to physiological pacing will be allowed in the following situations: coronary sinus cannot be cannulated; no lateral or posterolateral branches; or phrenic stimulation.
Interventions
Physiologic pacing to achieve QRS shortening. If the patient has indication of stimulation (AV block), a backup lead will be implanted in the right ventricle. All patients will have a lead placed in the right atrium (except those that have permanent atrial fibrillation).
Biventricular Resynchronization Therapy is the use of a pacemaker with two endocardial leads placed in the right atrium and right ventricle. The third lead is placed in a tributary of the coronary sinus.
Eligibility Criteria
You may qualify if:
- The patient must indicate their acceptance to participate in the study by signing an informed consent document.
- The patient must be ≥ 18 years of age.
- Left bundle branch block, QRS ≥130 and FEVI \<=35% (Indication of cardiac resynchronization IA or IB ESC Guidelines). No indication of stimulation for AV block.
- Patients with indication of resynchronization therapy for ventricular dysfunction and indication of cardiac stimulation for AV block according to ESC Guidelines (IA ESC Guidelines).
- Non-left bundle branch block, QRS ≥150 and FEVI \<=35% (Indication of cardiac resynchronization IIaB ESC Guidelines).
You may not qualify if:
- Myocardial infarction, unstable angina or cardiac revascularization during the previous 3 months.
- Pregnancy.
- Participating currently in a clinical investigation that includes an active treatment.

- The patient will be explained to be randomized to either of the two branches. The type of therapy applied will not be communicated to the patient. The follow-up will be the same in the two branches. During the visits it will not be said which therapy has been applied.
