--- abstract: "Tachycardia induced tachycardias are not common in clinical practice, and it is believed that most cases of double tachycardia are coincidental. The existence of two different tachycardias in the same patient almost always poses problems in the electrophysiology laboratory. However, in rare instances, the emergence of a second tachycardia can actually provide invaluable information about the first one. In this report, we describe a 30-year-old woman who presented with palpitations. Electrophysiological study revealed that atrial programmed stimulation at baseline induced right ventricular outflow tract (RVOT) tachycardia and supraventricular tachycardia. The study also showed that each of the tachycardias was able to induce the other. A short run of RVOT tachycardia during supraventricular tachycardia was able to entrain the latter. This finding provided important information about the nature of the supraventricular tachycardia, which proved to be atrioventricular nodal reentrant tachycardia. Both of these tachycardias were successfully ablated, and the patient’s palpitations disappeared.\n" altloc: - http://www.ipej.org/0402/pirat.htm chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: [] creators_name: - family: Ozin given: Bülent honourific: '' lineage: '' - family: Pirat given: Bahar honourific: '' lineage: '' - family: Müderrisoglu given: Haldun honourific: '' lineage: '' date: 2004-04 date_type: published datestamp: 2005-04-17 department: ~ dir: disk0/00/00/42/33 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: - family: Singh given: Balbir honourific: '' lineage: '' - family: Lokhandwala given: Yash honourific: '' lineage: '' - family: Francis given: Johnson honourific: '' lineage: '' - family: Gupta given: Anup honourific: '' lineage: '' eprint_status: archive eprintid: 4233 fileinfo: /style/images/fileicons/text_html.png;/4233/1/pirat.htm|/style/images/fileicons/application_pdf.png;/4233/2/pirat.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: 'Non-sustained ventricular tachycardia, supraventricular tachycardia, double tachycardia.' lastmod: 2011-03-11 08:55:57 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: 2 pagerange: 92-96 pubdom: TRUE publication: Indian Pacing and Electrophysiology Journal publisher: Indian Pacing and Electrophysiology Group refereed: TRUE referencetext: |- 1.
