Based on Coumel's law, an accessory pathway\u2010mediated mechanism was initially suspected for both tachycardias. However, the wide QRS tachycardia was ultimately confirmed to be ventricular tachycardia. Although Coumel's law may aid in the diagnosis of tachycardias with alternating QRS widths, potential confounding factors must be carefully considered to prevent misdiagnosis.<\/jats:p>","DOI":"10.1111\/pace.70155","type":"journal-article","created":{"date-parts":[[2026,3,13]],"date-time":"2026-03-13T17:25:11Z","timestamp":1773422711000},"page":"1124-1128","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Is Coumel's Law Always True?"],"prefix":"10.1111","volume":"49","author":[{"given":"Jia","family":"He","sequence":"first","affiliation":[{"name":"Department of Cardiology The Second Xiangya Hospital of Central South University  Changsha China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhihong","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Cardiology The Second Xiangya Hospital of Central South University  Changsha China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenjiang","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Cardiology The Second Xiangya Hospital of Central South University  Changsha China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,3,13]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.83.5.1649"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2007.09.020"},{"issue":"4","key":"e_1_2_11_4_1","first-page":"423","article-title":"Reciprocating Tachycardia in Overt and Latent Preexcitation.
