Recruiting NA Left Bundle Branch Block

New treatment option for Left Bundle Branch Block

Official title UHF ECG in LBBB and Response to CRT Prediction

ClinicalTrials.gov ID: NCT07057544

What this study is testing

What it's testing
The main objective of the project is to demonstrate that in patients with heart failure and QRS complex of nonRBBB morphology lasting over 130 ms, UHF-ECG can differentiate patients with trueLBBB from IVCD better than existing approaches based on the assessment of QRS complex morphology and duration from 12-lead ECG. Another goal of the proposed study is to demonstrate that trueLBBB patients will benefit more from CRT using left bundle branch pacing than from CRT using biventricular pacing.
