Our aim was to determine whether venticulo\u2010atrial (VA) conduction during SVT may be a possible mechanism for ST depression (STd) in SVT.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Patients undergoing SVT ablation (2010\u20132012) were analyzed (n = 72).Typical atrioventricular node reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT) were included. Those with STd were compared to those without STd. VA interval length, tachycardia cycle length (TCL), and retrograde P\u2010wave activation during SVT were assessed. Retrograde P waves arriving simultaneously with the ST segment (PWST) during SVT were considered, whenever an atrial electrogram (measured from the high right atrium) was \u201con time\u201d with the ST segment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Patients with STd during SVT presented longer VA intervals than those without STd (VA 100 \u00b1 37 ms vs VA 69 \u00b1 22 ms; P = 0.006). No differences in TCL were observed (TCL 333 \u00b1 35 ms vs TCL 360 \u00b1 22 ms; P = 0.1). PWST was observed in 38.5% of patients with AVNRT and STd versus 0% in those without STd. The TCL was similar in both groups (355 \u00b1 25 ms vs 334 \u00b1 18 ms; P = 0.1). In patients with AVRT and STd, PWST was present in 81% of cases versus 0% in those without STd. The TCL was also similar (330 \u00b1 29 ms vs 346 \u00b1 17 ms; P = 0.1).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>STd during SVT is observed at long VA intervals when the retrograde P wave matches the ST segment, without dependence on the TCL. This suggests that STd is not necessarily rate dependent but a result of a fusion between the ST segment and the P wave.<\/jats:p><\/jats:sec>","DOI":"10.1111\/pace.12394","type":"journal-article","created":{"date-parts":[[2014,4,3]],"date-time":"2014-04-03T02:22:52Z","timestamp":1396491772000},"page":"1100-1105","source":"Crossref","is-referenced-by-count":8,"title":["The Retrograde P\u2010Wave Theory: Explaining ST Segment Depression in Supraventricular Tachycardia by Retrograde AV Node Conduction"],"prefix":"10.1111","volume":"37","author":[{"given":"SANTIAGO","family":"RIVERA","sequence":"first","affiliation":[{"name":"Division of Cardiology Centre Hospitalier Universitaire de Sherbrooke  Sherbrooke Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MARIA DE LA","family":"PAZ RICAPITO","sequence":"additional","affiliation":[{"name":"Division of Cardiology Centre Hospitalier Universitaire de Sherbrooke  Sherbrooke Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"DIEGO","family":"CONDE","sequence":"additional","affiliation":[{"name":"Division of Cardiology Instituto Cardiovascular de Buenos Aires  Buenos Aires Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MARIANO BADRA","family":"VERDU","sequence":"additional","affiliation":[{"name":"Division of Cardiology Centre Hospitalier Universitaire de Sherbrooke  Sherbrooke Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JEAN FRAN\u00c7OIS","family":"ROUX","sequence":"additional","affiliation":[{"name":"Division of Cardiology Centre Hospitalier Universitaire de Sherbrooke  Sherbrooke Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F\u00c9LIX AYALA","family":"PAREDES","sequence":"additional","affiliation":[{"name":"Division of Cardiology Centre Hospitalier Universitaire de Sherbrooke  Sherbrooke Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,4,2]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"323","article-title":"Incidence and clinical significance of ST segment depression in supraventricular tachycardia","volume":"6","author":"Imrie JR","year":"1990","journal-title":"Can J Cardiol"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(96)00013-7"},{"key":"e_1_2_7_4_1","first-page":"206","article-title":"Significance of ST\u2010segment depression during supraventricular tachycardia.
