The gain-of-function Scn5a+/DeltaKPQ mutation in the cardiac Na(+) channel causes human long QT type 3 syndrome (LQT3) associated with ventricular arrhythmogenesis. The K(ATP) channel-opener nicorandil (20muM) significantly reduced arrhythmic incidence in Langendorff-perfused Scn5a+/Delta hearts during programmed electrical stimulation; wild-types (WTs)(More)
The recently described exchange protein directly activated by cAMP (Epac) has been implicated in distinct protein kinase A-independent cellular signalling pathways. We investigated the role of Epac activation in adrenergically mediated ventricular arrhythmogenesis. In contrast to observations in control conditions (n = 20), monophasic action potentials(More)
OBJECTIVES Transmucosal fentanyl is used to treat transient exacerbations of cancer pain. Several immediate release products are available, presented as intranasal sprays, sublingual and buccal tablets, or lozenges. These are not interchangeable, creating potential for medication errors. We compared the incidence of medication errors in a simulated scenario(More)
