DT was more likely to be conducted for new implants compared with impulse generator replacements (71% vs 32%, P = 0.0001), but was similar for primary and secondary prevention indications (64% vs 63%, P = NS). Among patients not having DT, the reason(s) given were: considered unnecessary (44%); considered unsafe, mainly due to persistent atrial fibrillation (37%); lack of an anesthetist (20%); and, patient or physician preference (6%).\n                  <\/jats:p>\n                  <jats:p>When performed, DT consisted of a single successful shock \u2265 10J below maximum device output in 65% of cases. A 10J safety\u2010margin was met by 97% of patients, requiring system modification in 2.3%. Major perioperative complications occurred in 4.4% of patients having DT versus 6.6% of patients not having DT (P = NS). ICD insertion was $844 more expensive for patients having DT (P = 0.16), largely due to increased costs ($28,017 vs $24,545) among patients having impulse generator replacement (P = 0.02).<\/jats:p>\n                  <jats:p>\n                    <jats:italic>Conclusions:<\/jats:italic>\n                    DT was not performed in a third of ICD implants, usually due to a perceived lack of need or relative contraindication.\n                    <jats:italic>(J Cardiovasc Electrophysiol, Vol. 21, pp. 177\u2010182, February 2010)<\/jats:italic>\n                  <\/jats:p>","DOI":"10.1111\/j.1540-8167.2009.01616.x","type":"journal-article","created":{"date-parts":[[2009,10,5]],"date-time":"2009-10-05T13:28:42Z","timestamp":1254749322000},"page":"177-182","source":"Crossref","is-referenced-by-count":35,"title":["Canadian Registry of ICD Implant Testing Procedures (CREDIT): Current Practice, Risks, and Costs of Intraoperative Defibrillation Testing"],"prefix":"10.1111","volume":"21","author":[{"given":"JEFF S.","family":"HEALEY","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"PAUL","family":"DORIAN","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.
