Undersensing and oversensing of events occur despite complex algorithms. The devices available have subtle differences, which may account for a difference in recorded characteristics. The electrocardiogram (ECG) characteristics of different monitors may influence their ability to correctly identify the events recorded. The objective is to compare the ECG characteristics of two commercially available implantable loop monitors and the ability to improve diagnostic accuracy. Two cohorts of patients were examined. Cohort 1 consisted of 30 patients with a Reveal LINQ I (Medtronic, Minneapolis, MN, USA) implanted, which was replaced with a BIOMONITOR III (Biotronik, Berlin, Germany) when the former had reached end of life. The new monitor was implanted at the same site in all patients. This provided a unique opportunity to compare ECGs obtained by both devices with no other confounding variable. Cohort 2 consisted of patients who had undergone implantation of either device at the discretion of the physician. This was therefore a retrospective analysis of 106 patients who had been implanted with one of the devices within a 2-year period. In both cohorts, we compared R-wave amplitude, the ability to accurately detect P-waves, and the frequency of undersensing and oversensing of events. In cohort 1, the mean R-wave was 0.35 ± 0.2 mV with the LINQ I as compared to 0.98 ± 0.4 with the BIOMONITOR III (<i>P</i> = .001). A P-wave in sinus rhythm was present in 19 (63%) subjects with the LINQ I implants versus 28 (93%) with the BIOMONITOR III implants (<i>P</i> = .004). Undersensing of events was noted in five (16%) patients with the LINQ I versus five (16%) with the BIOMONITOR III (<i>P</i> > .5). Oversensing was seen in 4 patients (13.33%) with the LINQ I versus 0 with the BIOMONITOR III (<i>P</i> = .012). In cohort 2, the mean R-wave with the BIOMONITOR III was significantly greater than with the LINQ I (0.65 ± 0.37 vs. 0.48 ± 0.38; <i>P</i> = .02). A visible P-wave was seen in 33 of 53 patients with the BIOMONITOR III as compared to 16 of 536 patients with the LINQ I monitor (<i>P</i> = .01). The number of patients identified as having under- or oversensing was, however, not significantly different (<i>P</i> = .08) in this cohort. In both patient cohorts, the BIOMONITOR III was noted to have significantly greater R-wave amplitude as compared with the LINQ I. A visible P-wave was also more commonly seen in patients with a BIOMONITOR III. In the paired cohort, but not in the unpaired cohort, the BIOMONITOR III was less likely to oversense R-waves. There was no significant difference in undersensing between the devices.</p>","PeriodicalId":36299,"journal":{"name":"Journal of Innovations in Cardiac Rhythm Management","volume":"16 1","pages":"6167-6172"},"PeriodicalIF":0.0,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11784397/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143081351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, extraction can be risky if the device is in an unfavorable position. We present a challenging case of a Nanostim LP (NLP) (Abbott Medical Inc., Abbott Park, IL, USA) placed 8 years prior to removal and subsequent replacement with an AVEIR LP (ALP) (Abbott). A 72-year-old man received an NLP in 2015 for persistent atrial fibrillation with bradycardia. The NLP could not be interrogated in our office. An external event monitor demonstrated persistent atrial fibrillation with bradycardia and pauses. A premature battery depletion of the NLP was suspected. An ALP was chosen for replacement. On a computed tomography scan of the chest, the NLP was seen in the mid-free wall of the right ventricle, and its proximal portion abutted the tricuspid annulus. The AVEIR retrieval catheter (ARC) was used for retrieval. Multiple attempts were made to snare the device, yet it proved difficult due to poor placement and button tissue formation. The snare became damaged, and a second ARC was needed. On the successful attempt, the NLP was snared proximally and permitted docking. We advanced the protective sleeve over the NLP body, but resistance was observed due to tissue growth. Counterclockwise torsion was applied, and the device disconnected. Once the NLP was in linear orientation, the protective sleeve was eventually positioned over its body, allowing removal. The ALP was then installed without difficulty or structural complications. This report shows the importance of proper LP placement in the right ventricular septal wall. LP removal can be performed safely, yet complications can arise based on the age and location of the LP. The ARC can be successfully used to extract non-AVEIR LPs with evidence of docking button tissue growth. Similar interventions should exercise caution when attempting extraction and subsequent implantation.</p>","PeriodicalId":36299,"journal":{"name":"Journal of Innovations in Cardiac Rhythm Management","volume":"15 12","pages":"6126-6129"},"PeriodicalIF":0.0,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11717154/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142972441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
