Ventricular Excitation in Experimental Bundle-Branch Block

Ventricular excitation in experimental bundle-branch block.

Multipoint 1 recording apparatus has been used to study the pattern of ventricular excitation in experimental bundle-branch block. After block, the wave of activation spreads uniformly from the contralateral ventricle across the septum to the free wall of the homolateral ventricle. Septal activation consumes more time than in the normal. Changes occur in the site and extent of early endocardia!...

Studies on the Mechanism of Ventricular Activity IV. Ventricular Excitation in Segmental and Diffuse Types of Experimental Bundle-Branch Block

Controlled studies of ventricular excitation were performed in dogs exhibiting various degrees of right imd left bundle-branch block. Increases in the intraventricular conduction time during complete bundle-branch block are attributed to free wall as well as septal factors. Incomplete bundle-branch block may be either segmental or diffuse. In the segmental type, delayed excitation is present in...

The Electrocardiogram in Ventricular Hypertrophy and Bundle-Branch Block

DR. KOSSMANN: Our panel has been assigned the task of unravelling for you, to the best of our ability, the dual problems of the electrocardiogram in ventricular hypertrophy and in bundle-branch block. For the achievement of this formidable assignment we have been allotted exactly 45 minutes. That we will succeed in clarifying a subject that was destined, almost from its inception a half century...
