Differing effects of right ventricular pacing and left bundle branch block on left ventricular function.
OBJECTIVE To compare the different effects of right ventricular pacing and classic left bundle branch block on left ventricular function. DESIGN Retrospective and prospective study of 48 patients by electrocardiography, and M mode, cross sectional, and Doppler echocardiography. SETTING A tertiary cardiac referral centre. PATIENTS 48 patients (age range 21 to 89 years, 15 women), 24 with a...
متن کاملLeft ventricular endocardial pacing improves resynchronization therapy in canine left bundle-branch hearts.
BACKGROUND We investigated the benefits of the more physiological activation achieved by left ventricular (LV) endocardial pacing (ENDO) as compared with conventional epicardial (EPI) LV pacing in cardiac resynchronization therapy. METHODS AND RESULTS In 8 anesthetized dogs with experimental left bundle-branch block, pacing leads were positioned in the right atrium, right ventricle, and at 8 ...
متن کاملLeft ventricular activation time in left ventricular hypertrophy and in left bundle-branch block.
Simultaneous tracings of right and left ventricular leads were taken in 6 dogs with experimentally produced left bundle-branch block, and in 30 clinical cases of left ventricular hypertrophy. In the experimental study it was found that the initial phase of the QRS complex in the right epicardial lead did not change its configuration or its duration after the production of left bundle-branch blo...
متن کاملCardiac 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. ...
