“…Enlargement of the atria was identified as a factor of higher prevalence of AF and lower likelihood of sinus rhythm restoration and maintenance [24,25]. Former studies have shown that the size of atria is correlated with mean AS amplitude and AS stability in VDD pacemakers [26,27]. This finding is consistent with our observations in this ICD population.…”

(PP, periprocedural), predischarge (IHFU, in-hospital follow-up) (3.15 vs. 1.2 mV, p = 0.045, 7.53 vs. 3.8 mV, p < 0.001 and 5.63 vs. 2.44 mV, p = 0.017 for PP measurements, IHFU and AFU, respectively). There was a significant negative correlation between AS-PP and short RA dimension (RADs) (r = -0.56, p = 0.02), AS-IHFU and RA area (RAA) (r = -0.45, p < 0.05), AS-AFU and long RA dimension (RADl) (r = -0.46; p = 0.02), 48, p = 0.02), p < 0.01). There was no relationship between AS and other right heart dimensions. Conclusions: Larger RA size and low sensing dipole location were associated with lower AS amplitude in single-lead dual chamber ICD. (Cardiol J 2017; 24, 6: 671-676) and 3-6 months after the procedure (AFU, ambulatory follow-up). Results were related to atrial dipole position in the right atrium (RA) on the basis of chest X-ray examination as well as right heart dimensions at echocardiography. Results: Twenty-four patients were included into final analysis. In 14 (58.3%) patients, sensing dipole was located in regions 1 and 2 of the RA. AS amplitude was greater in regions 1 and 2 when compared to other locations

“…[17] The prevalence of atrial undersensing varied among different studies. [8] Santini et al [4] reported stable atrial signals over time in every physical activity, while extensive variation of atrial signal amplitude between postures was reported in another study. [18] Marchandise et al [19] found that up to one-third of VDD pacemaker patients could not maintain good atrial sensing after a mean follow-up of 2 years, which could mostly be ameliorated by increasing the atrial sensitivity.…”

“…[4,5] However, available data about whether VDD is a good alternative to DDD are inconsistent. [6,7] Several trials have shown a comparable efficacy of VDD and DDD pacing, but with a lower cost for VDD, [6,8–10] while others demonstrated that up to one-third of patients with VDD failed to maintain AV synchronous pacing after years of follow-up.…”

Long-term outcome in patients receiving permanent pacemaker implantation for atrioventricular block

A permanent pacemaker (PPM) with dual chamber pacing (DDD) offers atrioventricular synchronization for patients with atrioventricular block (AVB). Single lead atrial synchronous ventricular pacing mode (VDD) is an alternative, but there are concerns about its efficacy and risk of atrial undersensing. Whether VDD can be a good alternative in patients with AVB remains unknown. The aim of the present study was to compare the long-term risk of mortality of VDD with DDD pacing.A total of 207 patients undergoing PPM implantations for AVB with VDD mode were enrolled from 2000 to 2013. Another 828 age- and sex-matched patients undergoing DDD implantations during the same period of time were selected as the control group in a 1 to 4 ratio. The study endpoint was mortality.A total of 1035 patients (64.3% male) were followed up for 46.5 ± 43.2 months. The mean ages were 75.0 years for VDD, and 74.9 years for DDD. The Kaplan–Meier survival analysis showed no significant difference in long-term survival between the VDD and DDD groups (log-rank P = 0.313). After adjustment for baseline characteristics, the VDD and DDD groups had a similar long-term prognosis with an adjusted hazard ratio of 0.875 (P = 0.445). Further analyses for the risk of cardiovascular and noncardiovascular deaths also showed no significant differences between the 2 groups.The long-term prognosis of VDD mode is comparable to that of DDD mode. Single lead VDD can be considered as an alternative choice in patients with AVB without sinus nodal dysfunction.

“…Even in the case of an EGM being of relatively low amplitude, most VDD pacemakers allow programming of a high sensitivity (0.1 mV for all models of our study, except for Medtronic Thera which was 0.18 mV) which may prevent atrial undersensing, without an undue risk of oversensing [7]. If intermittent atrial undersensing is present, it has been shown that if this occurs in < 10% of beats, exercise test results or quality-of-life are not affected [8].…”
