Right Bundle-Branch Block and the Velocity of the Electrocardiogram
Archives of Internal Medicine, 1967WITH the development of computer techniques applied to electrocardiographic analyses, emphasis has been shifted to quantitative rather than qualitative interpretation of the electrocardiogram. Conduction defects represent one of the areas of electrocardiography where quantitation is most desirable.

Cardiac contusion and right bundle branch block
Journal of the American College of Emergency Physicians, 1977In a case of transient right bundle branch block due to nonpenetrating chest trauma, this abnormal electrocardiographic finding was the sole manifestation of cardiac contusion. There is a high frequency of occult cardiac contusion and routine electrocardiography is recommended in the evaluation of nonpenetrating chest trauma.

Right bundle branch block with right ventricular hypertrophy
The American Journal of Cardiology, 1959Abstract Thirty-eight cases of proved right ventricular hypertrophy were studied. Right intracavitary leads obtained near the anterior papillary muscle demonstrated some degree of right bundle branch block in addition to the hypertrophy in thirty-four of the cases.

The Early Signs of Right Bundle Branch Block
Chest, 1985Complete right bundle branch block manifests with a rSR' configuration in right orientated leads and a duration of 0.12 sec or longer. Incomplete right bundle branch block is perceived as this classic rSr' configuration and a duration of less than 0.12 sec.

Expert Review of Cardiovascular Therapy, 2013
The so-called 'masquerading' type of right bundle branch block is caused by the simultaneous presence of a high-degree left anterior fascicular block often accompanied with severe left ventricular enlargement and/or fibrotic block in the anterolateral wall of the left ventricle.

The term right bundle branch block (RBBB) was originally anatomically and functionally strictly defined. The term is based on the experiments of Eppingek and Rothberger with animals (1909), in which the right branch of the atrioventricular bundle was cut.

Site of functional right bundle branch block
American Heart Journal, 1980An in vivo canine heart was prepared by utilizing a temporary right heart bypass system to place close bipolar electrodes along the course of the right bundle branch. Activation within the right bundle could be recorded in up to six locations along the right bundle with premature supraventricular stimulation that caused functional right bundle branch ...

Journal of Electrocardiology, 1981
Summary The purpose of this study was to examine the long term prognosis of ‘so-called’ incomplete right bundle branch block (RSR1 in V1 or V2) from the perspective of the risk of occurrence of complete right bundle branch block. The Manitoba Study consists of a cohort of 3983 men who have been followed with regular examinations, including ECGs since

Complete Right Bundle-Branch Block
Postgraduate Medicine, 1967Complete right bundle-branch block is characterized electrocardiographically by three identifying patterns. The typical vectorcardiographic and electrocardiographic features and some of the possible variations in right bundle-branch block are discussed.
