Radiofrequency ablation is a method widely used in human medicine for the permanent treatment of arrhythmias. In veterinary medicine, there are only a few centers worldwide that use this treatment method in dogs. This article presents the experiences of a Polish center in treating supraventricular and ventricular arrhythmias using this method. The first electrophysiological study and ablation were performed using an analog electrophysiological system; subsequent procedures were performed with the aid of a computerized system, and the last three procedures were performed using a 3D electroanatomical system. A total of 14 radiofrequency ablation procedures were performed on dogs weighing 10 to 33 kg, aged 9 months to 9 years, of various sexes and breeds. Fifty percent of the dogs that underwent ablation had both clinical and echocardiographic signs of tachycardia-induced cardiomyopathy. Three dogs required a re-ablation procedure. Complete elimination of clinically significant arrhythmias was achieved in 13 of 14 dogs, while one dog showed partial procedural success. No significant or permanent complications were observed in any of the dogs. Radiofrequency ablation procedures for arrhythmias are effective and safe.<\/jats:p>","DOI":"10.3390\/vetsci13080760","type":"journal-article","created":{"date-parts":[[2026,7,30]],"date-time":"2026-07-30T13:55:11Z","timestamp":1785419711000},"page":"760","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["One Polish Center\u2019s Experience of Catheter Ablation for Cardiac Arrhythmias in Dogs"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7899-3936","authenticated-orcid":false,"given":"Agnieszka","family":"Noszczyk-Nowak","sequence":"first","affiliation":[{"name":"Department of Internal Medicine and Clinic of Diseases of Horses, Dogs and Cats, Faculty of Veterinary Medicine, University of Environmental and Life Sciences, 50-366 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6688-3051","authenticated-orcid":false,"given":"Piotr","family":"Frydrychowski","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Clinic of Diseases of Horses, Dogs and Cats, Faculty of Veterinary Medicine, University of Environmental and Life Sciences, 50-366 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8130-0432","authenticated-orcid":false,"given":"Justyn","family":"Gach","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Clinic of Diseases of Horses, Dogs and Cats, Faculty of Veterinary Medicine, University of Environmental and Life Sciences, 50-366 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zuzanna","family":"Wojtczak","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Clinic of Diseases of Horses, Dogs and Cats, Faculty of Veterinary Medicine, University of Environmental and Life Sciences, 50-366 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4795-2418","authenticated-orcid":false,"given":"Alicja","family":"Cepiel-Ko\u015bmieja","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Clinic of Diseases of Horses, Dogs and Cats, Faculty of Veterinary Medicine, University of Environmental and Life Sciences, 50-366 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Artur","family":"Fuglewicz","sequence":"additional","affiliation":[{"name":"Cardiac Lab, Jozef Strus City Hospital, 61-285 Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Krzysztof","family":"Nowak","sequence":"additional","affiliation":[{"name":"Institute of Heart Diseases, Medical University of Wroclaw, 50-556 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"653","DOI":"10.1056\/NEJM198303173081112","article-title":"Catheter Technique for Closed-Chest Ablation of an Accessory Atrioventricular Pathway","volume":"308","author":"Weber","year":"1983","journal-title":"N.
