Sinus Impulse Propagation in Normal Human Atria. Introduction: Better understanding of atrial propagation during sinus rhythm (SR) in normal hearts under the most normal physiologic conditions may be propaedeutic to pathophysiologic studies of complex atrial arrhythmias. In this study, qualitative and quantitative analyses of sinus impulse propagation in both atria were performed by electroanatomic mapping in patients with no organic heart disease who were undergoing an electrophysiologic… 
Electroanatomic Analysis of Sinus Impulse Propagation in Normal Human Atria
TLDR
Two patterns of sinus node activation are described as a spindle-shaped activation over the superior portion of the crista terminalis and a U-shaped orientation with an anterior projection in the region of the right atrial (RA) appendage.
P Wave and the Substrates of Arrhythmias Originating in the Atria.
TLDR
Electrocardiogram reveals ectopic or retrograde atrial activation, wandering pacemaker activity, or artificial pacemaker-mediated atrial depolarization in patients with atrioventricular arrhythmias.
Normal Atrial Activation and Voltage During Sinus Rhythm in the Human Heart: An Endocardial and Epicardial Mapping Study in Patients with a History of Atrial Fibrillation
TLDR
The sequence of endocardial and epicardial activation and voltage of the atria during normal sinus rhythm is evaluated to evaluate the three‐dimensional contributions to human atrial activation in sinus Rhythm.
Atrial Activation Mapping in Sinus Rhythm in the Clinical Electrophysiology Laboratory:
Introduction: The high posterolateral right atrium (RA) is considered the “sinus node area,” but we lack information on endocardial atrial activation in sinus rhythm. We studied RA and left atrial
Endocardial electro-anatomic mapping in healthy horses: Normal sinus impulse propagation in the left and right atrium and the ventricles.
TLDR
A 3D electro-anatomical mapping system was used to evaluate the qualitative and quantitative depolarisation patterns and correlation to the surface ECG of both the atrial and ventricular endocardium in seven healthy horses in sinus rhythm under general anaesthesia.
Electroanatomic mapping of right atrial activation in patients with and without paroxysmal atrial fibrillation.
TLDR
The previously reported conduction delay in the posteroseptal region in patients with paroxysmal AF might locate within the posterior inter-atrial septum, according to this study.
Human Study of Biatrial Electrical Coupling: Determinants of Endocardial Septal Activation and Conduction Over Interatrial Connections
TLDR
Electrical coupling of the RA and LA in humans is predominantly provided by muscular connections at the level of Bachmann's bundle and the coronary sinus, which is asynchronous and discordant, usually without contralateral conduction during sinus rhythm or atrial pacing.
Interatrial conduction in patients with paroxysmal atrial fibrillation and in healthy subjects.
TLDR
Susceptibility to paroxysmal lone AF is associated with propagation of atrial signal to LA via margin of fossa ovalis or multiple pathways, and altered and alternative conduction pathways may contribute to pathogenesis of lone AF.
Three‐Dimensional Mapping of Right Atrial Activation During Sinus Rhythm and Its Relationship to Endocardial Architecture
TLDR
This study describes global RA endocardial activation patterns using high‐density mapping and compares the results with underlying endocardIAL architecture.
Deterioration of interatrial conduction in patients with paroxysmal atrial fibrillation: electroanatomic mapping of the right atrium and coronary sinus.
TLDR
Interatrial conduction at the posteroparaseptal region across the CS ostium was significantly slower in patients with paroxysmal atrial (AF) fibrillation than in control patients, further supporting the link between interatrial Conduction deterioration and paroxYSmal AF.

The purpose of this study was to ascertain the role of specific anatomic structures on reentry induction and maintenance in Morphologically Realistic Atria.
Use of electroanatomic mapping to delineate transseptal atrial conduction in humans.
TLDR
Three distinct sites of early right atrial activation may be demonstrated during left atrial pacing, in accord with anatomic muscle bundles, which may have relevance for maintenance of atrial flutter or fibrillation.

Functional assessment was limited in these initial patient studies, but correspondence with similar observations in extensive previous canine studies supports the concept of a widely distributed atrial pacemaker complex in man.

TLDR
Atrial septal maps explain why surgical dissection, or properly positioned small cryolesions placed in the region of the AV node, can ablate AV node reentrant tachycardia without altering normal AV node function and suggest that atrial flutter is amenable to control by surgical techniques.

The findings of this study demonstrate that epicardial and endocardial activation can be discordant in specific regions and that discordance increases with abnormal activation sequences.
Spread of excitation from the atrium into thoracic veins in human beings and dogs.
TLDR
The results suggest that the Lewis theory of atrial flutter—that is, that the venae cavae present an obstacle around which excitation waves progress—is untenable since wave fronts propagate in the venous muscle in a manner that quickly renders the tissue refractory by the merging and collision of waves.
