H-V Intervals in Left Bundle-Branch Block

H-V intervals in left bundle-branch block. Clinical and electrocardiographic correlations.

Left 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. ...

Left 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...

assessment of qt and jt intervals in patients with left bundle branch block

conclusions right ventricular pacing increases the qt interval without increasing the jt interval. our results confirm that jtc, as an index of repolarization, is independent of ventricular depolarization. therefore, it can be applied for predicting qtc in patients with lbbb. results stimulation from the rva increased the qtc from 456.20 ± 38.63 ms to 530.67 ± 47.73 ms at a cl of 600 (p < 0.000...
