“…The P-cells in the Bachmann bundle are similar to the P-cells in the sinoatrial and/or AV node 1 ; therefore, the Bachmann bundle potentially could be associated with increased occurrence of automaticity. It is generally difficult to record direct Bachmann bundle potentials because it is a distinct structure separate from the atrium; however, a previous report suggested that the Bachmann bundle and the epicardial surface of the left atrial appendage could be accessed by a catheter located in the pulmonary artery 2 . In addition, mapping of both pulmonary arteries can include far-field atrial potentials of both atrial regions, which can provide useful information to differentiate right and left atrial tachycardia 3 .…”

“…Previous papers have shown that atrial electrograms recorded from the main pulmonary artery trunk correspond to local activation of the left atrial appendage, 18,19) that atrial electrograms recorded from the proximal left pulmonary artery correspond to local activation of the left lateral atrium, 20) and that atrial electrograms recorded from the RPA correspond to local activation of Bachmann's bundle. 21) Thus, atrial electrograms of the LPA represent left lateral atrial activation, and atrial electrograms of the right pulmonary artery represents left septal activation.…”

Atrial premature depolarizations (APDs) triggering atrial fibrillation (AF) originate from mainly the pulmonary veins (PVs), but, in some cases, atrial ectopic beats (AEBs) triggering AF originate from the right atrium (RA) or the superior vena cava. Accurate identification of the origin of APDs in the PVs by means of RA and coronary sinus mapping is difficult. Purpose: The aim of this study was to identify the origin of AEBs triggering AF before transseptal catheterization. Electrode catheters were placed in the posteroseptal RA (PSRA), right pulmonary artery (RPA), left pulmonary artery (LPA), and esophagus in 10 patients with paroxysmal AF. We analyzed endocardial electrograms from the PSRA, RPA and LPA, and epicardial electrograms from the esophagus. The origin of the AEBs in the PVs was determined before PV ablation by mapping 4 PVs simultaneously. Four AEBs originated from the left superior PV (LSPV), 2 from the left inferior PV (LIPV), 4 from the right superior PV (RSPV), 2 from the RA or superior vena cava. In AEBs originating from the RA, the PSRA activation was the earliest and it proceeded in a cranial to caudal direction. In AEBs originating from the RUPV, RPA was the earliest. The esophageal activation sequence was in a cranial to caudal direction. In AEBs from the LSPV, LPA was the earliest and the esophageal activation sequence proceeded in a cranial to caudal direction. In AEDs from LIPV, LPA was the earliest, and the esophageal activation sequence was nearly simultaneous. Atrial activation sequences from the PSRA, RPA, LPA, and esophageal catheters can accurately identify the location of the initiating foci of AF before a transseptal procedure.

“…Similar information useful in timing the atrial depolarization sequence may be obtained with indirect mapping of left atrial depolarization. These mapping points involve recording of atrial electrograms from esophageal (high and mid) recording sites, coronary sinus both proximal and distal sites, and the right pulmonary artery location [2,3]. It has been shown that the spread of excitation over the atrial epicardial surface occurs through concentric isochrones [4].…”

“…Unless the specific left atrial sites from which the recordings are made can be adequately described and their location confirmed, the value of these measurement is of little value. Schaal et al, in a recent article, have shown that electrograms obtained from indirect left atrial recording sites provide a useful and satisfactory quantification of intratrial conduction times [3].…”

5 ] conduction times are prolonged in patients with a history of atrial flutter. The values obtained, each representing the time needed for the sinus node impulse to reach the LA, differ markedly. In order to compare the values of HRA to LA conduction time obtained by different workers, the LA recording site must be known. More detailed mapping of LA depolarization will allow easier comparison of the atrial conduction times obtained from different LA sites.A patent foramen ovale occurs in 15-28% of normal individuals [ 131 and at the same location in the interatrial septum as a secundum atrial septa1 defect. These defects are easily crossed by acatheter introduced from the femoral vein [14]. Thus a high incidence of catheter passage across patent foramen ovales is expected during electrophysiological studies. These interatrial communications should be routinely sought, as they allow recording of a high LA electrogram, which provides useful clinical information regarding the sequence of atrial depolarization.
