Atrial fibrillation (AF) ablation was the most common procedure at 29%. EP procedure rates increased by 21% (to 353 per million in 2018), predominantly due to AF ablation rates increasing by 46%. Ventricular tachycardia ablation rates increased by 41% but only comprised 8% of procedures. There was a striking difference in the growth of EP procedure rates in the public compared to the private sector (4% vs 106%), as well as considerable differences in EP procedure and AF ablation rates across the public EP centres. NZ had lower ablation rates compared to countries with similar healthcare expenditure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>There has been a substantial increase in EP procedure and AF ablation rates in NZ and international trends suggest this growth will continue. However, there is considerable variation in procedure rates and growth trends between EP centres, highlighting inequities in access within the country.<\/jats:p><\/jats:sec>","DOI":"10.1111\/imj.14781","type":"journal-article","created":{"date-parts":[[2020,2,11]],"date-time":"2020-02-11T10:17:40Z","timestamp":1581416260000},"page":"1247-1252","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Recent trends in cardiac electrophysiology and catheter ablation in New Zealand"],"prefix":"10.1111","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3546-4863","authenticated-orcid":false,"given":"Fang Shawn","family":"Foo","sequence":"first","affiliation":[{"name":"Department of Cardiology Middlemore Hospital  Auckland New Zealand"},{"name":"Green Lane Cardiovascular Service Auckland City Hospital  Auckland New Zealand"},{"name":"Department of Cardiology North Shore Hospital  Auckland New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin K.","family":"Stiles","sequence":"additional","affiliation":[{"name":"Department of Cardiology Waikato Hospital  Hamilton New Zealand"},{"name":"Department of Medicine University of Auckland  Auckland New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geoffrey C.","family":"Clare","sequence":"additional","affiliation":[{"name":"Department of Cardiology Christchurch Hospital  Christchurch New Zealand"},{"name":"Department of Medicine University of Otago  Christchurch New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nigel","family":"Lever","sequence":"additional","affiliation":[{"name":"Green Lane Cardiovascular Service Auckland City Hospital  Auckland New Zealand"},{"name":"Department of Medicine University of Auckland  Auckland New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Darren","family":"Hooks","sequence":"additional","affiliation":[{"name":"Department of Medicine University of Otago  Christchurch New Zealand"},{"name":"Department of Cardiology Wellington Hospital  Wellington New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Heaven","sequence":"additional","affiliation":[{"name":"Department of Cardiology Middlemore Hospital  Auckland New Zealand"},{"name":"Green Lane Cardiovascular Service Auckland City Hospital  Auckland New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dean","family":"Boddington","sequence":"additional","affiliation":[{"name":"Department of Cardiology Tauranga Hospital  Tauranga New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Heart Rhythm New Zealand (HRNZ)","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,10,27]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"1830","article-title":"Tachycardie permanente par rhythme reciproque.
