Abstract:
:Increased cardiac output in response to beta-adrenergic receptor stimulation is achieved by rapid alteration of the activity of cardiac ion channels, pumps, and exchangers. Over the past decade, the discovery of macromolecular complexes, which include the ion channels and pumps and the kinases that control their level of phosphorylation, has led to an increased understanding of the molecular mechanisms behind the cardiac adrenergic response. The increased understanding has led to the discovery of a new long QT gene encoding an accessory protein in one of these macromolecular complexes. This article briefly reviews the major components of the beta-adrenergic pathway in the heart and discusses the direction of current and future research.

HEART RHYTHM文献大全abstract::Quinolone antibiotics have potentially serious proarrhythmic effects. The effects on intracardiac potassium channels result in QT interval prolongation, leading to torsades de pointes. Evidence suggests fluoroquinolones cause QT-mediated proarrhythmia, and weak evidence links ciprofloxacin with QT-mediated arrhythmias...
