Roxithromycin and other macrolide antimicrobials are widely used for a broad variety of infections such as upper respiratory tract infection and community acquired pneumonia. Prolongation of the QT interval, torsade de pointes polymorphic ventricular tachycardia, and sudden death are well described but little known adverse reactions common to all macrolides. We report the case of a 72 year old ...
The QT interval represents ventricular depolarisation and repolarisation. Prolongation of this interval can lead to life-threatening complications. These can include arrhythmias such as Torsades de Pointes and Ventricular Fibrillation, which may ultimately lead to death. Many risk factors have been identified in prolonging the QT interval, one of which is medication commonly used in the treatme...
Voriconazole can prolong the QT interval contributing to life-threatening cardiac arrhythmia. Torsades de pointes is an uncommon but serious complication of voriconazole use which may be under-recognised. We present torsades de pointes in two patients with underlying haematological malignancy being treated for invasive fungal infection with voriconazole. Patients receiving voriconazole should b...
OBJECTIVES To explore the effect of aging on cardiac toxicity specifically the interaction of age and antipsychotic drugs to alter the QT interval. METHODS THE MEDLINE DATABASES WERE SEARCHED USING THE OVIDSP PLATFORMS WITH THE SEARCH STRATEGY: "QT interval" or "QT" and "age" or "aging". The entry criteria were: over 10,000 apparently healthy individuals with data on both sexes; QT interval c...
Patients with LQTS (long QT syndrome) with a mutation in a cardiac ion channel gene, leading to mild-to-moderate channel dysfunction, may manifest marked QT prolongation or torsade de pointes only upon an additional stressor. A 59-year-old woman had marked QT prolongation and repeated torsade de pointes 3 months after initiation of probucol, a cholesterol-lowering drug. We identified a single b...
