Relationship between left bundle branch block patterns and super-response to cardiac resynchronization therapy in patients with heart failure

Relationship between left bundle branch block patterns and super-response to cardiac resynchronization therapy in patients with heart failure

Aim . To assess a relationship of left bundle branch block (LBBB) patterns defined by electrocardiography (ECG) and echocardiography with super-response (SR) to cardiac resynchronization therapy (CRT). Material and methods . Sixty patients (mean age, 54,5±10,4 years) were examined at baseline and du...

Zusammenfassung:Aim . To assess a relationship of left bundle branch block (LBBB) patterns defined by electrocardiography (ECG) and echocardiography with super-response (SR) to cardiac resynchronization therapy (CRT). Material and methods . Sixty patients (mean age, 54,5±10,4 years) were examined at baseline and during follow-up (10,6±3,6 months). Patients were divided into groups: group I (n=31) — decrease of left ventricular end-systolic volume (ESV) ≥30% (super-responders) and II group (n=29) — decrease of LV ESV
