Article Synopsis
  • The existing ECG criteria for diagnosing left bundle branch block (LBBB) struggle to effectively differentiate between true complete LBBB (t-LBBB) and false complete LBBB (f-LBBB).
  • Researchers conducted a study involving 37 patients scheduled for cardiac resynchronization therapy (CRT), examining the QRS notch width in lateral leads to improve diagnostic accuracy.
  • They found significant differences in how the QRS notch peaks correlated with the electrical activity of the heart between t-LBBB and f-LBBB groups, offering insights for more reliable diagnosis.

Objectives: We aimed to evaluate the feasibility of left ventricular electroanatomical mapping to choose between left bundle branch area pacing (LBBAP) or coronary venous pacing (CVP).

Background: There are several ways to achieve left ventricular activation in cardiac resynchronization therapy (CRT): LBBAP and CVP are two possible methods of delivering CRT. However, the criteria for choosing the best approach remains unknown.

Objective: To evaluate left univentricular (LUV) pacing for cardiac resynchronization therapy (CRT) using a rate-adaptive atrioventricular delay (RAAVD) algorithm to track physiological atrioventricular delay (AVD).

Methods: A total of 72 patients with congestive heart failure (CHF) were randomized to RAAVD LUV pacing versus standard biventricular (BiV) pacing in a 1: 1 ratio. Echocardiography was used to optimize AVD for both groups.

Background: The aim of this study was to investigate the effect of cardiac resynchronization therapy (CRT) with right ventricular (RV) sense triggered left ventricular (LV) pacing for chronic heart failure (CHF).

Methods: Thirty patients who were eligible for the Class I indication of CRT were enrolled and the informed consents were signed. Left ventricular ejection fraction (LVEF), diastolic mitral flow velocity time integral (VTI), mitral regurgitation flow VTI, and aortic valve flow VTI were measured with GE Vivid 7 (GE Medical, Milwaukee, WI, USA) before and after CRT.

Background: Cardiac resynchronization therapy (CRT) is a major breakthrough in therapy for advanced heart failure patients; however, a number of key clinical research questions remain, perhaps most importantly the issue of why apparently suitable patients do not respond to CRT.

Methods: Seven patients, six males and one female, aged (56.43 +/- 6.
