Asynchronism in contraction of the ventricles in the so-called common type of bundle-branch block: Its bearing on the determination of the side of the significant lesion and on the mechanism of split first and second heart sounds
TLDR
The hypothesis that in the common type of bundle-branch block there is asynchronism in the beginning of ejection from the two ventricles due to delay on the left side is supported.About:

Left Bundle Branch Block Etiologic, Hemodynamic, and Ventriculographic Considerations
TL;DR: The onset of left ventricular contraction was delayed in the patients with left bundle branch block, but the period of isovolumic contraction was normal in those without severe underlying disease.

The relationship between electrical and mechanical events in the cardiac cycle of man.
TL;DR: With direct measurements from within the right heart chambers and pulmonary artery, coupled with peripheral arterial pulse wave and electrocardiographic recordings, the nqrmal course of electrical and mechanical events may be more clearly defined in man and abnormalities in contraction and conduction of the diseased heart may be further elucidated.

The muscular reactions of the mammalian ventricles to artificial surface stimuli
TL;DR: The muscular reactions of the mammalian ventricles to localized artificial stimuli have not been studied with the degree of precision that the subject merits, and a reasonable familiarity with these communications is essential in order to follow the data and conclusions presented in this paper.

The excitatory process observed in the exposed human heart
TL;DR: The results suggest that the conducting tracts in the right ventricle of man may differ from those of the dog, and the electrocardiogram is dominated by right ventricular effects and vice versa.

The order of ventricular excitation in human bundle-branch block☆☆☆
TL;DR: The chief ventricular upstroke of semidirect leads, in which the exploring electrode is placed close to the ventricular surface, corresponds to the intrinsic deflection of direct leads from the ventricles in which a single contact is placed upon the muscle.

An analysis of the spread of the excitation wave in the human ventricle
TL;DR: The more extended introduction of the method among American clinicians and a revision of some of the ideas developed in that paper on the propagation of the wave of electronegativity in the human heart are introduced.
