  Arrhythmogenic mechanisms of non-sedating antihistamines Left click: open entry/Right click: save entry
Mechanistic studies showed that blockade of IKr channels by non-sedating anti-histamines leads to prolongation of the monophasic action potential (QT interval on surface electrocardiogram) which may then induce the development of early after-depolarization and dispersion of repolarisation leading to torsades de pointes through re-entry mechanism.
