Background: During left bundle branch area pacing (LBBAP), several markers of electrical synchrony, (V6 R-wave peak time (RWPT), aVL-RWPT, and the V6-V1 interpeak interval), are commonly used to assess left bundle branch (LBB) capture. Nevertheless, the relationship between these electrocardiographic (ECG) measurements and mechanical synchrony remains poorly understood.

Objective: We aimed to analyze the association between electrical parameters from the paced QRS complex and mechanical performance assessed through 2D strain and myocardial work (MW) indices, following LBBAP implantation.

Objective: To investigate two conditions that have been poorly investigated in the medical literature before in the context of atrial fibrillation: the coexistence and association of right or left bundle branch block and axis deviation in patients with permanent atrial fibrillation compared to the control group of healthy subjects with sinus rhythm.

Material And Methods: We conducted an analytic, retrospective observational study performed at Ziv Medical Center, Safed, Israel, collecting data from medical history records of all patients that have been diagnosed with permanent atrial fibrillation versus healthy controlled patients with normal sinus rhythm. We analyzed their ECGs in order to assess the presence of any bundle branch block and/or axis deviation.
