Cardiac pacing in left bundle branch/bifascicular block patients.
The primary concern in patients with bifascicular block is the increased risk of progression to complete heart block. Further, an additional first-degree A-V block in patients with bifascicular block or LBBB might increase the risk of block progression. Anesthesia, monitoring and surgical techniques can induce conduction defects and bradyarrhythmias in patients with pre-existing bundle branch b...
متن کاملLeft Bundle Branch Block
Coronary angiography, cine left ventriculography, and the cardiovascular hemodynamics of 24 patients with left bundle branch block were studied. Seven patients were found to have significant coronary artery disease, always severe. Five had cardiomyopathy and seven had valvular disease. Only those with coronary artery disease or cardiomyopathy had abnormal left ventricular contraction patterns. ...
متن کاملLeft bundle branch block.
A RECENT STUDY of the prognosis of patients with left bundle branch block (L.B.B.B.) suggested that life expectancy was extremely short (Smith and Hayes 1965). While in general L.B.B.B. has a sinister reputation, we have been struck by a few individuals who have survived many years with L.B.B.B., and we thought an analysis of some of the material available at the Royal Victoria Hospital, Belfas...

متن کاملAlternating bundle branch block during atrial bigeminy.
Alternate patterns of ventricular excitation may occur with any type of supraventricular bigeminy. It is a physiologic phenomenon that depends on the rate dependency of bundle-branch refractoriness and the linking phenomenon related to concealed retrograde penetration of aberrantly conducted beats into their own blocked bundle branch [1–3]. An alternate pattern of ventricular activation can onl...
