Postoperative interrogation revealed both primary and secondary S\u2010ICD vectors inappropriately regarded sinus rhythm as \u201cnoise,\u201d and the alternate vector significantly undersensed sinus rhythm. The S\u2010ICD was reinterrogated using high\u2010resolution capture to visually confirm EMI with a dominant frequency in both the primary and secondary vectors of 46.67\u00a0Hz that fell within the S\u2010ICD operational range of 9\u201360\u00a0Hz. The 46.67\u00a0Hz frequency correlated with the HVAD operational speed of 2,800 RPM. The HVAD pump speed was increased from 2,800 to 3,000 RPM, resulting in a dominant frequency of 50\u00a0Hz. The notch filter is nonprogrammable in S\u2010ICDs. However, the built\u2010in filter is 50\u00a0Hz for countries in European time zones as opposed to 60\u00a0Hz in US time zones due to differences in the anticipated noise from electrical sources within each continent. Thus, the S\u2010ICD time zone was reprogrammed from EST to GMT, which reduced the notch filter from 60\u00a0 to 50\u00a0Hz, resulting in S\u2010ICD successfully eliminating EMI when the patient was in a supine position. The EMI interference was still intermittently present in the upright patient position. This case demonstrates the utility of high\u2010resolution electrogram capture to identify the source and frequency of EMI in S\u2010ICD and offers a potential avenue to troubleshoot dominant frequency oversensing by changing the device time zone.<\/jats:p>","DOI":"10.1111\/jce.13433","type":"journal-article","created":{"date-parts":[[2018,1,24]],"date-time":"2018-01-24T13:46:43Z","timestamp":1516801603000},"page":"477-481","source":"Crossref","is-referenced-by-count":21,"title":["Troubleshooting electromagnetic interference in a patient with centrifugal flow left ventricular assist device and subcutaneous implantable cardioverter defibrillator"],"prefix":"10.1111","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2158-2797","authenticated-orcid":false,"given":"Asim S.","family":"Ahmed","sequence":"first","affiliation":[{"name":"St. Vincent Medical Group St. Vincent Hospital  Indianapolis IN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Parin J.","family":"Patel","sequence":"additional","affiliation":[{"name":"St. Vincent Medical Group St. Vincent Hospital  Indianapolis IN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shiv","family":"Bagga","sequence":"additional","affiliation":[{"name":"St. Vincent Medical Group St. Vincent Hospital  Indianapolis IN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jasen L.","family":"Gilge","sequence":"additional","affiliation":[{"name":"St. Vincent Medical Group St. Vincent Hospital  Indianapolis IN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Schleeter","sequence":"additional","affiliation":[{"name":"St. Vincent Medical Group St. Vincent Hospital  Indianapolis IN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Baqir A.","family":"Lakhani","sequence":"additional","affiliation":[{"name":"St. Vincent Medical Group St. Vincent Hospital  Indianapolis IN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ashwin K.","family":"Ravichandran","sequence":"additional","affiliation":[{"name":"St. Vincent Medical Group St. Vincent Hospital  Indianapolis IN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steve","family":"Donnelley","sequence":"additional","affiliation":[{"name":"Boston Scientific  St. Paul MN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Venu","family":"Allavatam","sequence":"additional","affiliation":[{"name":"Boston Scientific  St. Paul MN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric N.","family":"Prystowsky","sequence":"additional","affiliation":[{"name":"St. Vincent Medical Group St. Vincent Hospital  Indianapolis IN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Benzy J.","family":"Padanilam","sequence":"additional","affiliation":[{"name":"St. Vincent Medical Group St. Vincent Hospital  Indianapolis IN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,2,27]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/anec.12181"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.116.004633"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.113.000240"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.14503\/THIJ-14-4166"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.14503\/THIJ-14-4795"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2013.04.020"}],"container-title":["Journal of Cardiovascular Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fjce.13433","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jce.13433","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,25]],"date-time":"2023-09-25T22:12:56Z","timestamp":1695679976000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/jce.13433"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,2,27]]},"references-count":6,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2018,3]]}},"alternative-id":["10.1111\/jce.13433"],"URL":"https:\/\/doi.org\/10.1111\/jce.13433","archive":["Portico"],"relation":{},"ISSN":["1045-3873","1540-8167"],"issn-type":[{"value":"1045-3873","type":"print"},{"value":"1540-8167","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,2,27]]}}}
