Patient 1, a 50 year old man with episodic palpitations and dizziness for 10 years, exhibited initiation of idiopathic ventricular tachycardia (VT) by atrial fibrillation (AF). Patient 2, a 43 year old woman with a structurally normal heart but recurrent palpitations for one year, demonstrated fusion and capture beats during simultaneous VT and AF. An explanation is given as to why the latter phenomenon is rarely observed.<\/jats:p>","DOI":"10.1136\/heart.84.1.e1","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T06:37:59Z","timestamp":1027751879000},"page":"e1-e1","source":"Crossref","is-referenced-by-count":6,"title":["Capture and fusion beats during atrial fibrillation and ventricular tachycardia"],"prefix":"10.1136","volume":"84","author":[{"given":"A","family":"Nabar","sequence":"first","affiliation":[{"name":"Department of Cardiology, Academic Hospital Maastricht, P Debyelaan 25, 6202 AZ, Post bus 5800, Maastricht, Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L-M","family":"Rodriguez","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Academic Hospital Maastricht, P Debyelaan 25, 6202 AZ, Post bus 5800, Maastricht, Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C","family":"Timmermans","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Academic Hospital Maastricht, P Debyelaan 25, 6202 AZ, Post bus 5800, Maastricht, Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K","family":"Kattenbeck","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Academic Hospital Maastricht, P Debyelaan 25, 6202 AZ, Post bus 5800, Maastricht, Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H J J","family":"Wellens","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Academic Hospital Maastricht, P Debyelaan 25, 6202 AZ, Post bus 5800, Maastricht, Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2000,7,1]]},"reference":[{"key":"2025100704332218000_84.1.e1.1","unstructured":"Wellens HJJ Rodriguez LM Smeets JLRM (1995) Ventricular tachycardia in structurally normal hearts. in Cardiac electrophysiology.
