The prevalence and clinical characteristics of the patients who fail this TMS is unknown.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and Results<\/jats:title>\n                    <jats:p>QRS\u2010TMS was done in 230 consecutive ICD outpatients (75% male, age 57 \u00b1 15 years) without an indication for cardiac pacing, using an ECG simulating the 3 sensing vectors of the S\u2010ICD (TMS\u2010ECG). Patients were defined suitable when at least 1 sensing vector was considered appropriate in both supine and standing position. In total, 7.4% of patients, who were all male, were considered not suitable for a S\u2010ICD according to the TMS\u2010ECG. Independent predictors for TMS failure were hypertrophic cardiomyopathy (HCM; odds ratio [OR] 12.6), a heavy weight (OR 1.5), a prolonged QRS duration (OR 1.5) and a R:T ratio &lt;3 in the lead with the largest T wave on a standard 12\u2010lead surface ECG (OR 14.6).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In patients without an indication for pacing, 7.4% would have been not suitable for a S\u2010ICD according to the TMS. HCM, a heavy weight, a prolonged QRS duration and a R:T ratio &lt;3 in the ECG lead with the largest T wave were independently associated with TMS failure. These data might alert physicians that selection of patients for a S\u2010ICD should be considered with special caution in certain patient groups, because they may not satisfy ECG criteria for adequate sensing.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/jce.12343","type":"journal-article","created":{"date-parts":[[2013,12,9]],"date-time":"2013-12-09T15:26:43Z","timestamp":1386602803000},"page":"494-499","source":"Crossref","is-referenced-by-count":121,"title":["Which Patients Are Not Suitable for a Subcutaneous ICD: Incidence and Predictors of Failed QRS\u2010T\u2010Wave Morphology Screening"],"prefix":"10.1111","volume":"25","author":[{"given":"LOUISE R.A.","family":"OLDE NORDKAMP","sequence":"first","affiliation":[{"name":"Department of Cardiology Academic Medical Center  Amsterdam the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JOPPE L.F.","family":"WARNAARS","sequence":"additional","affiliation":[{"name":"Department of Cardiology Academic Medical Center  Amsterdam the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"KIRSTEN M.","family":"KOOIMAN","sequence":"additional","affiliation":[{"name":"Department of Cardiology Academic Medical Center  Amsterdam the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JORIS R.","family":"de GROOT","sequence":"additional","affiliation":[{"name":"Department of Cardiology Academic Medical Center  Amsterdam the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"BOUDEWIJN R.A.M.","family":"ROSENM\u00d6LLER","sequence":"additional","affiliation":[{"name":"Department of Cardiology Academic Medical Center  Amsterdam the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ARTHUR A.M.","family":"WILDE","sequence":"additional","affiliation":[{"name":"Department of Cardiology Academic Medical Center  Amsterdam the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"REINOUD E.","family":"KNOPS","sequence":"additional","affiliation":[{"name":"Department of Cardiology Academic Medical Center  Amsterdam the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2014,1,7]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(97)00355-0"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-138-6-200303180-00007"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa0909545"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2011.06.007"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.112.975268"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2012.06.053"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2012.02432.x"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2011.02199.x"},{"key":"e_1_2_7_10_1","unstructured":"Cameron Health.SQ\u2010RXTMPulse Generator.
