Procedural success rate as well as long-term freedom from recurrent VT is modest after RFA for VT in ischaemic heart disease. However, ICD discharges are significantly reduced after RFA, and a considerable proportion of patients remain free from recurrent VT during the long-term follow-up.
RFA is effective for treating idiopathic VA with and without AIC, with high rates of long-term freedom from VA and symptomatic relief. We found more patients with AIC had left ventricle VA.
IntroductionAntipsychotics are associated with the polymorphic ventricular tachycardia, Torsade's de pointes, which in worst case can lead to sudden cardiac death. The QTc interval is used as a clinical proxy for Torsade's de pointes. QTc interval is prolonged by monotherapy with antipsychotic, but it is unknown if the QTc interval is prolonged further with antipsychotic polypharmacy.ObjectivesTo investigate the associations between QTc interval and antipsychotic mono- and polypharmaceutical treatment, respectively, in schizophrenic patients.AimsTo learn more about the impact of antipsychotics on the QTc interval.MethodsAn observational cohort study of unselected patients with schizophrenia visiting outpatient facilities in the Region of Central Jutland, Denmark. Patients were enrolled from January 2013 through March 2015 with follow-up until June 2015. Data was collected from clinical interviews and clinical case records.ResultsECGs were available in 58 patients receiving antipsychotic treatment. We observed no difference in average QTc interval for the whole sample of patients receiving monotherapy or polypharmacy (P = 0.29). However, women presented longer QTc-interval on polypharmacy than on monotherapy (P = 0.01).ConclusionWe recommend an increased focus on monitoring the QTc interval in woman with schizophrenia receiving antipsychotics as polypharmacy.Disclosure of interestThe authors have not supplied their declaration of competing interest.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
