“…Iori et al [21] showed stable AS during 200-day follow-up but the population of the study was limited to only 13 patients. In the largest, so far, multicenter study including 116 patients with ICD DX system, Safak et al [22] achieved appropriate AS in 93.8% of patients. In this study, mean preamplified P-wave amplitudes ranged from 5.0 mV to 6.1 mV.…”

(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

“…ICDs. [23][24][25] One major limitation of the DX system is that it does not offer atrial pacing. However, data have shown that only 3% to 5% of patients implanted with a single-chamber ventricular ICD require an atrial lead upgrade for sinus node dysfunction during long term follow-up.…”

IntroductionSubclinical atrial fibrillation (AF), in the form of cardiac implantable device‐detected atrial high rate episodes (AHREs), has been associated with increased thromboembolism. An implantable cardioverter‐defibrillator (ICD) lead with a floating atrial dipole may permit a single lead (DX) ICD system to detect AHREs. We sought to assess the utility of the DX ICD system for subclinical AF detection in patients, with a prospective multicenter, cohort‐controlled trial.Methods and ResultsOne hundred fifty patients without prior history of AF (age 59 ± 13 years; 108 [72%] male) were enrolled into the DX cohort and implanted with a Biotronik DX ICD system at eight centers. Age‐, sex‐, and left ventricular ejection fraction‐matched single‐ and dual‐chamber ICD cohorts were derived from a Cornell database and from the IMPACT trial, respectively. The primary endpoint were AHRE detection at 12 months. During median 12 months follow‐up, AHREs were detected in 19 (13%) patients in the DX, 8 (5.3%) in the single‐chamber, and 19 (13%) in the dual‐chamber cohorts. The rate of AHRE detection was significantly higher in the DX cohort compared to the single‐chamber cohort (P = .026), but not significantly different compared to the dual‐chamber cohort. There were no inappropriate ICD therapies in the DX cohort. At 12 months, only 3.0% of patients in the DX cohort had sensed atrial amplitudes less than 1.0 mV.ConclusionUse of a DX ICD lead allows subclinical AF detection with a single lead DX system that is superior to that of a conventional single‐chamber ICD system.
