RATIONALE Drug-induced prolongation of the corrected QT interval (QTc) may lead to serious and potentially life-threatening ventricular tachyarrhythmia, such as torsades de pointes (Tdp), which is worthy of clinical attention. Here, we report 1 case of Tdp after a coadministration of fluoxetine and amiodarone. PATIENT CONCERNS A 62-year-old Chinese male who placed with the implanted cardiover...
OBJECTIVES Prolongation of the QT interval is a risk factor for sudden death. Selective serotonin-reuptake inhibitor antidepressants can prolong the QT interval and are widely used by pregnant women. Whether antenatal exposure to selective serotonin-reuptake inhibitor causes QT prolongation in offspring is unknown. The aim of this study was to determine the effect of maternal use of selective s...
The letter from Dr. Venkatesan (1) correctly notes that several months before publishing our article (2) in Anesthesia & Analgesia, Yildirim et al. (3) had published an article regarding the influence of desflurane on some variables of cardiac ventricular repolarization. Yildirim et al.’s paper was published after our manuscript had been submitted to Anesthesia & Analgesia, and we had no knowle...
AIMS The coronary collateral circulation has a beneficial role regarding all-cause and cardiac mortality. Hitherto, the underlying mechanism has not been clarified. The aim of this prospective study was to assess the effect of the coronary collateral circulation on electrocardiogram (ECG) QTc time change during short-term myocardial ischaemia. METHODS AND RESULTS A total of 150 patients (mean...
BACKGROUND Although many electrocardiographic abnormalities have been reported previously, prolonged QTC interval represented as the most important ECG finding in patients with liver cirrhosis. Echocardiography can detect structural cardiac abnormalities in cirrhotic patients. OBJECTIVES The present study aimed to determine the correlation between QTC prolongation and echocardiographic findin...
PURPOSE Although the ABCB1 (P-glycoprotein) drug transporter is a constituent of several blood-tissue barriers (i.e., blood-brain and blood-nerve), its participation in a putative blood-heart barrier has been poorly explored. ABCB1 could decrease the intracardiac concentrations of drugs that cause QT prolongation and cardiotoxicity. EXPERIMENTAL DESIGN ABCB1-related romidepsin transport kinet...
Introduction. Several studies show that hypoglycemia causes QT interval prolongation. The aim of this study was to investigate the effect of QT measurement methodology, heart rate correction, and insulin types during hypoglycemia. Methods. Ten adult subjects with type 1 diabetes had hypoglycemia induced by intravenous injection of two insulin types in a cross-over design. QT measurements were d...
Antipsychotic (AP) drugs have the potential to cause prolongation of the QT interval corrected for heart rate (QTc). As this risk is dose-dependent, it may be associated with the number of AP drugs concurrently prescribed, which is known to be associated with increased cumulative equivalent AP dosage. This study analysed whether AP dose mediates the relationship between polypharmacy and QTc int...
