background: diagnosis of coronary artery disease (cad) in patients with left bundle branch block (lbbb) is considered as a challenge in cardiology due to the low accuracy of noninvasive methods such as basal and stress electrocardiography (ecg). this diagnostic challenge can be reduced but not eliminated using dipyridamole as a stress method instead of exercise. the aim of this study was to ass...

Electrocardiograms of 2500 consecutive patients who died in hospital were reviewed in order to study the relation ofcomplete left bundle-branch block to pathological determinants ofanatomical left ventricular hypertrophy. Of these, 43 patients demonstrated complete left bundle-branch block and all but two had anatomical left ventricular hypertrophy at necropsy. -Mean values of total heart weigh...

Abstract Funding Acknowledgements Type of funding sources: Private company. Main source(s): Medtronic Background Left bundle branch area pacing(LBBAP) has been introduced as a more physiological pacing alternative to anti-bradycardia and an biventricular in cardiac resynchronization therapy (CRT). LBBAP is the common denominator left ventricular septal pacing(LVSP) pacing(LBBP). In LVSP, there ...

Presenting electrocardiograms of intermittent left bundle branch block in a 60-year-old female.

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...
