To study the influence of left bundle branch block (LBBB) on the signal-averaged
electrocardiogram (SAECG), quantitative and qualitative analyses of SAECG parameters …

Background and hypothesis: A hypothesis was formulated that regional delayed activation of
the right ventricle, as seen in incomplete right bundle‐branch (IRBBB) aberrancy, may …

In this study, we consider the proposition that the criteria for the electrocardiographic (ECG)
diagnosis of left bundle-branch block (LBBB) be revised, a proposition born from analysis of …

Background Left bundle branch block (LBBB) is commonly associated with structural heart
disease and left ventricular dysfunction. We propose that the QRS duration and degree of …

The effects of right ventricular pacing, which simulated left bundle branch block (BBB), on
QRST time-integral values of 12-lead electrocardiograms (ECGs) were examined, and the …

Left ventricular (LV) dyssynchrony (LVdys) is a necessary condition for successful cardiac
resynchronization therapy (CRT). Despite left bundle branch block (LBBB) representing a …

BACKGROUND: There are no established criteria to differentiate new from old left bundle
branch block (LBBB). This complicates management of patients with LBBB and suspected …

The frontal plane QRS axis of electrocardiograms during “normal” conduction and left
bundle branch block were compared in 231 patients with intermittent left bundle branch …

Examination of ECGs in patients with intermittent left bundle branch block (LBBB) may
provide insight into mechanisms and cause of LBBB. In this study, we obtained ECG files of …

To determine whether any associated electrocardiographic findings in persons with newly
acquired complete left bundle branch block (LBBB) correlate with the prevalence of …
