The two most common etiologies of paroxysmal supraventricular tachycardia (SVT) are atrioventricular node reentry tachycardia (AVNRT) and atrioventricular reciprocating tachycardia (AVRT).<\/jats:p><jats:p><jats:italic>Hypothesis<\/jats:italic>: We postulated that adenosine might have different effects on the termination of AVNRT vs. AVRT, and that these differences might assist in the noninvasive differentiation between these diagnoses.<\/jats:p><jats:p><jats:italic>Methods<\/jats:italic>: Fifty\u2010nine patients referred for the diagnosis and treatment of SVT were included in the study. All patients had SVT induced during electrophysiology testing, and each patient received adenosine during SVT. The adenosine dose, time to tachycardia termination, and site of tachycardia termination were recorded. Seventeen patients required isoproterenol administration to initiate SVT. This subset of patients was compared with those not requiring isoproterenol.<\/jats:p><jats:p><jats:italic>Results<\/jats:italic>: There was no statistically significant difference in the adenosine dose or time to tachycardia termination when comparing patients with AVNRT with those with AVRT. All patients with AVNRT had termination of tachycardia in the antegrade direction with final activation in the atria. Patients requiring isoproterenol for tachycardia initiation experienced tachycardia termination significantly faster than those not requiring isoproterenol, although there was no difference in the dose of adenosine required for termination.<\/jats:p><jats:p><jats:italic>Conclusion<\/jats:italic>: These data demonstrate that patients with dual AV node physiology and AVNRT do not have altered sensitivity to adenosine compared with patients with AVRT and normal AV nodes. Further investigation will be required to determine the clinical utility of the significantly shorter time to tachycardia termination for patients receiving isoproterenol.<\/jats:p>","DOI":"10.1002\/clc.4960211009","type":"journal-article","created":{"date-parts":[[2009,2,4]],"date-time":"2009-02-04T02:26:02Z","timestamp":1233714362000},"page":"743-745","source":"Crossref","is-referenced-by-count":3,"title":["Comparison of adenosine effects on atrioventricular node reentry and atrioventricular reciprocating tachycardias"],"prefix":"10.1002","volume":"21","author":[{"given":"J.","family":"Kevin DONAHUE","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Orias","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ronald D.","family":"Berger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gordon F.","family":"Tomaselli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John H.","family":"Lawrence","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hugh","family":"Calkins","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2009,2,3]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.83.5.1499"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.RES.59.4.437"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(84)80295-8"},{"key":"e_1_2_1_5_2","first-page":"141","article-title":"Comparative clinical and electrophysiologic effects of adenosine and verapamil on termination of paroxysmal supraventricular tachycardia","volume":"46","author":"Sethi KK","year":"1994","journal-title":"Ind Heart J"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(97)00386-0"},{"key":"e_1_2_1_7_2","first-page":"I\u2010284","article-title":"Differential effect of adenosine on antegrade fast, antegrade slow and retrograde fast pathways in patients with atrioventricular nodal reentrant tachycardia (abstr)","volume":"94","author":"Lai WT","year":"1996","journal-title":"Circulation"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.4065\/70.3.274"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-113-2-104"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(89)90573-0"}],"container-title":["Clinical Cardiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fclc.4960211009","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/clc.4960211009","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,28]],"date-time":"2023-10-28T23:10:16Z","timestamp":1698534616000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/clc.4960211009"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1998,9]]},"references-count":9,"journal-issue":{"issue":"10","published-print":{"date-parts":[[1998,9]]}},"alternative-id":["10.1002\/clc.4960211009"],"URL":"https:\/\/doi.org\/10.1002\/clc.4960211009","archive":["Portico"],"relation":{},"ISSN":["0160-9289","1932-8737"],"issn-type":[{"value":"0160-9289","type":"print"},{"value":"1932-8737","type":"electronic"}],"subject":[],"published":{"date-parts":[[1998,9]]}}}
