“…This is surprisingly not in line with many efforts to avoid ventricular pacing not only by device programming but also by so phisticated pacemaker algorithms. Recently, Wa tabe et al in the study of 102 dualchamber pace maker recipients with SSS concluded that low septal pacing results in shorter atrioventricular conduction [23]. This is concordant with results of that Miyazaki et al observed in a group of 202 pa tients [24].…”

in a surface electrocardiogram. A slower inter atrial conduction takes place in the coronary si nus. The physiological left atrial contraction de lay amounts to 22 ± 11 ms in relation to the right atrium [1][2][3].The interatrial conduction disorders are rela tively common in sick sinus syndrome patients, which contribute to atrial arrhythmias, in par The implantation of a permanent pacemaker alters the electrophysiological and hemodynam ic relations in a heart. The electrical physiologi cal activation of the atria comes from the sino atrial node. The left atrium activation is achieved throughout the conductive tissue layer called the Objectives. This study was aimed to assess the influence of the atrial pacing site on interatrial and atrioventricular conduction as well as the percentage of ventricular pacing in patients with sick sinus syndrome implanted with atrioventricular pacemaker. Material and Methods. The study population: 96 patients (58 females, 38 males) aged 74.1 ± 11.8 years were divided in two groups: Group 1 (n = 44) with right atrial appendage pacing and group 2 (n = 52) with Bachmann's area pacing. We assessed the differences in atrioventricular conduction in sinus rhythm and atrial 60 and 90 bpm pacing, Pwave duration and percentage of ventricular pacing. Results. No differences in baseline Pwave duration in sinus rhythm between the groups (102.4 ± 17 ms vs. 104.1 ± 26 ms, p = ns.) were noted. Atrial pacing 60 bpm resulted in longer Pwave in group 1 vs. group 2 (138.3 ± 21 vs. 106.1 ± 15 ms, p < 0.01). The differences between atrioventricular conduction time during sinus rhythm and atrial pacing at 60 and 90 bpm were significantly longer in patients with right atrial appendage vs. Bachmann's pacing (44.1 ± 17 vs. 9.2 ± 7 ms p < 0.01 and 69.2 ± 31 vs. 21.4 ± 12 ms p < 0.05, respectively). The percentage of ventricular pacing was higher in group 1 (21 vs. 4%, p < 0.01). Conclusions. Bachmann's bundle pacing decreases interatrial and atrioventricular conduction delay. Moreover, the frequencydependent atrioventricular conduction lengthening is much less pronounced during Bachmann's bundle pacing. Right atrial appendage pacing in sick sinus syndrome patients promotes a higher percentage of ventricular pacing (Adv Clin Exp Med 2016, 25, 5, 845-850).

“… 11 RA septal pacing induces a shorter AV interval than right appendage pacing. 12 It is known that shortened QRS time after CRT implantation is associated with favorable clinical and echocardiographic responses. 13 QRS time was shorter in LV-only pacing than in biventricular pacing in case 1; therefore, LV-only pacing may be favorable in case 1.…”

“…Patients with conduction delays or blocks in the atria frequently experience first degree AV block. Moreover, they often have atrial lead implanted in the low interatrial septum to optimize paced AV delay 4 . However, when intrinsic sinus rhythm is incompletely preserved, sensed and paced atrial events may coexist, forming a large deviation.…”

A 74‐year‐old man experienced complete atrioventricular (AV) block 2 days after catheter ablation for right atrial (RA) macroreentrant tachycardia. We performed DDD pacemaker implantation with atrial septal pacing because other sites of pacing threshold were not acceptable. The maximum left ventricular outflow tract velocity time integral was 15.8 cm with sensed AV delay (40 ms) and 15.0 cm with paced AV delay (220 ms); however, this exceeded the pacemaker's maximum difference of 100 ms. We herein report the case of a large discrepancy in optimal AV delay intervals between sensed and paced atrial events, requiring consideration of proper pacemaker settings.

Atrial Pacing Site and Atrioventricular Conduction in Patients Paced for Sinus Node Disease

Abstract: Compared with RAA, LRAS pacing showed shorter AV interval in SND patients with or without 1st degree AV block and LA enlargement. This beneficial effect persisted through 1-year follow-up, and decreased cum%VP significantly.
