LBBB produces a wall motion abnormality that may mimic ischemic wall motion abnormality of interventricular septum. With careful evaluation of wall motion in the presence of LBBB, we can identify signs that help us to better differentiate ischemic wall motion abnormalities from LBBB.

1974年5月1日 · The specific echocardiographic abnormality demonstrated in left bundle branch block is a very dynamic posterior motion of the interventricular septum occurring within 0.04 seconds of the onset of the QRS and preceding the anterior motion of the posterior left ventricular wall during ventricular ejection.

This systematic review investigates the diagnostic and prognostic utility of coronary flow reserve (CFR) assessment through echocardiography in patients with left bundle branch block (LBBB), a condition known to complicate the clinical evaluation of coronary artery disease (CAD).

2014年7月10日 · The last case on the blog of LBBB with very high voltage was actually first identified as LBBB by ED bedside echo, which was done PRIOR to the ECG. The images were captured on one of our new ultrasound machines, with Speckle Tracking, which uses software to outline the movement of the myocardium, making it easier to see the wall motion.

Left bundle branch block (LBBB) is a rather common conduction disturbance, however seen with dismay by many cardiologists because of diagnostic difficulties in ischaemic syndromes, electrocardiographic exercise testing, in scintigraphic studies and so on.

2019年8月1日 · Left bundle branch block (LBBB) leads to mechanical dyssynchrony resulting in reduced cardiac performance. Despite the success of cardiac resynchronisation therapy (CRT) in these patients ( McMurray et al. 2012 ), it remains challenging to identify optimal inclusion criteria for CRT candidates, with the percentage of non-responders between 20% ...

2024年6月18日 · This systematic review investigates the diagnostic and prognostic utility of coronary flow reserve (CFR) assessment through echocardiography in patients with left bundle branch block (LBBB), a condition known to complicate the clinical evaluation of …

Three-dimensional echocardiography is a feasible and reproducible method for the quantification of left ventricular volumes, left ventricular ejection fraction and regional wall motion. Differences can be assessed between normal patients and patients with left bundle branch block. (Neth Heart J 2007;15:89-94.)

Stress echocardiography has a poor positive predictive value to identify significant angiographic CAD in higher-risk patients with LBBB; however, the negative predictive value for hard ischemic events is similar to patients without LBBB.

2020年11月25日 · Previous studies have shown that left bundle branch block (LBBB), as a relatively common electrocardiographic (ECG) abnormality, represents the condition with often non benign and sometimes adverse outcome. The Aim of our study was to determine the predictive value of a stress echocardiography test in patients with LBBB.
