TL;DR: Amiodarone proved safe in patients with severe congestive heart failure and severe myocardial damage and liberates patients from a rigid hourly schedule and provides for continuous antiarrhythmic control, days and even weeks after treatment is discontinued.

TL;DR: Bayley’s theory of conventional myocardial injury applies remarkably well to the analysis of injury of the intraventricular conducting fascicles, and SDD plays an important additional role in the conduction system.

TL;DR: The existence of these syndromes, which are termed altogether “trifascicular blocks”, provides one of the most valuable evidences of the anatomical and functional “ trilaterality” of the human intraventricular conduction system.

TL;DR: The syndrome of “right bundle branch block with intermittent left anterior and posterior hemiblock” is only one of the several possibilities of what the authors have named “intraventricular trifascicular blocks,” which will be considered in the second part of this paper.

TL;DR: Three prerequisites are necessary for the occurrence of either direct or incompletely concealed Wenckebach periods in the bundle branches: the opening beat should be normally conducted (in the affected bundle branch); the second beat should been conducted with a delay of no more than 0.04 to 0.06 sec; the damaged bundle branch should not be activated retrogradely in the closure beat.
