We studied six consecutive patients (age 60\u2009\u00b1\u200912 years; five males) with incomplete revascularization and mechanical support (extracorporeal membrane of oxygenation\u2009=\u20092; left ventricular assist device\u2009=\u20094) with VT\/VF refractory to lidocaine and amiodarone. Intravenous ibutilide was given as a last resort for management of their ventricular arrhythmias. Intravenous ibutilide (1\u20102\u2009mg) allowed restoration of sinus rhythm in three patients with persistent VF that were refractory to multiple defibrillation shocks. When the 24\u2010hour period before and after ibutilide administration was compared, this drug markedly reduced the number of required cardioversions\/defibrillations in all patients from 20\u2009\u00b1\u20099 to 0.7\u2009\u00b1\u20090.8 shocks (\n<jats:italic>P<\/jats:italic>\u2009=\u20090.036).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In patients with myocardial ischemia requiring hemodynamic support, intravenous Ibutilide demonstrates a potent antiarrhythmic effect and can facilitate defibrillation in patients with refractory VF.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jce.13835","type":"journal-article","created":{"date-parts":[[2018,12,23]],"date-time":"2018-12-23T05:31:03Z","timestamp":1545543063000},"page":"503-510","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Ibutilide for the control of refractory ventricular tachycardia and ventricular fibrillation in patients with myocardial ischemia and hemodynamic instability"],"prefix":"10.1111","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2916-9956","authenticated-orcid":false,"given":"Mauricio","family":"Sendra\u2010Ferrer","sequence":"first","affiliation":[{"name":"Penn State University Heart and Vascular Institute, Penn State University College of Medicine, The Milton S.
