The presenting electrocardiogram showed a wide QRS complex tachycardia with an irregular rhythm. The RR intervals were irregular, and there were more complex QRS waves than P waves. The patient was first diagnosed with ventricular tachycardia. The ECG during sinus rhythm revealed a complete right bundle-branch block. The patient underwent an invasive electrophysiological study and was then diagnosed with atrioventricular nodal reentrant tachycardia (AVNRT). Following successful slow pathway radiofrequency ablation (located at the anterior part of the coronary sinus ostium), tachycardia was no longer inducible.<\/jats:p>","DOI":"10.3389\/fphys.2025.1732486","type":"journal-article","created":{"date-parts":[[2026,1,23]],"date-time":"2026-01-23T06:48:19Z","timestamp":1769150899000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["The missing P waves in wide QRS tachycardia"],"prefix":"10.3389","volume":"16","author":[{"given":"Jiangying","family":"Mo","sequence":"first","affiliation":[{"name":"Guilin Hospital of the Second Xiangya Hospital of Central South University","place":["Guilin, Guangxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuan","family":"Jiang","sequence":"additional","affiliation":[{"name":"The Second Xiangya Hospital of Central South University","place":["Changsha, Hunan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuang","family":"Zhang","sequence":"additional","affiliation":[{"name":"The Second Xiangya Hospital of Central South University","place":["Changsha, Hunan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuping","family":"Li","sequence":"additional","affiliation":[{"name":"The Second Xiangya Hospital of Central South University","place":["Changsha, Hunan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mingxian","family":"Chen","sequence":"additional","affiliation":[{"name":"Guilin Hospital of the Second Xiangya Hospital of Central South University","place":["Guilin, Guangxi, China"]},{"name":"The Second Xiangya Hospital of Central South University","place":["Changsha, Hunan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,1,23]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"499","DOI":"10.1016\/0002-9149(78)90947-5","article-title":"Retrograde block during dual pathway atrioventricular nodal reentrant paroxysmal tachycardia","volume":"42","author":"Bauernfeind","year":"1978","journal-title":"Am.
