Beneficial Effects of Biatrial Pacing on Cardiac Function in Patients With Bradycardia - Tachycardia Syndrome

Cardiac hemodynamics and proinflammatory cytokines during biatrial and right atrial appendage pacing in patients with interatrial block

“…In our study, echocardiographic examination revealed higher VTI of the mitral inflow as well as aortic VTI during BiA vs. RAA pacing, which confirms with the observations made by Matsumoto et al [14]. It is known that BiA pacing improves atrial systolic function [16–19].…”

“…Biatrial (BiA) pacing is one of the methods of reducing IAB and decreasing the incidence of atrial tachyarrhythmias [7–9]. With respect to cardiac hemodynamics, however, the superiority of BiA over standard RAA pacing remains controversial as data from available studies are conflicting [10–14]. …”

Dual‐Site Right Atrial Pacing Increases Left Atrial Appendage Flow in Patients with Sick Sinus Syndrome and Paroxysmal Atrial Fibrillation

“…The lack of changes in left pulmonary vein (LPV) and MV mean velocities underlines that there was no alteration of overall transatrial flow during pacing and that the slightly elevated paced heart rate is unlikely to be responsible for LAA and E-wave flow variations. The study results are in line with the data from 1 trial 20 also showing accelerated LAA appendage flow with biatrial pacing immediately after cardioversion and a second trial, 21 which found the E-wave velocity reduced and cardiac output increased with biatrial pacing. For the biatrial configuration with simultaneous pacing from the right atrial appendage and the coronary sinus favorable hemodynamic effects indicating partial reversal of atrial stunning immediately after electrical cardioversion have recently been described by Takagi et al, 20 who demonstrated left atrial appendage flow to accelerate and transmitral A-wave velocity to increase when compared to sinus rhythm and to right atrial appendage pacing.…”

“…This is reflected in the findings of Ho et al, 23 who showed that A‐wave velocity and A‐wave filling during right atrial dual‐site DDD pacing were optimal at AV delays which had to be programmed to unusual low values. Matsumoto et al 21 explain the favorable changes of the LV inflow pattern during biatrial pacing primarily as a consequence of the improved left sided AV sequence. In the patient cohort of the present study truncated A‐waves due to short left sided AV activation times with sinus rhythm were not observed and LV filling appeared to be uncompromised during both, spontaneous rhythm and dual‐site right atrial pacing.…”

Atrial Function During Different Multisite Atrial Pacing Modalities in Patients With Bradycardia - Tachycardia Syndrome

“…Some investigators have suggested that multisite atrial pacing (MAP), which incorporates 1 electrode in the right atrial appendage (RAA) and the other in the coronary sinus (CS) ostium area (dualsite atrial pacing) or in the mid-or distal CS (bi-atrial pacing), might be more beneficial than conventional RAA pacing. [6][7][8] Recently, our group proposed a novel method of MAP incorporating the Bachmann's bundle (BB) and CS ostium region. 9 This novel pacing modality presumes "double electrical resynchronization" of the left atrium (LA) and its antiarrhythmic effect has been shown in patients with AF.…”
