 ===Triggered activity===
-'''Triggered activity''' vuren cellen twee keer, terwijl ze maar één keer gestimuleerd zijn. Dit is meestal het gevolg van zogenaamde ''nadepolarisaties'' (early of delayed afterdepolarisations EAD's / DAD's) door electrische onstabiliteit in de hartcelmembraam. Een typisch voorbeeld hiervan is [[#Torsade_de_pointes|Torsade de pointes]].
+During '''triggered activity''' heart cells contract twice, although they only have been activated once. This is often caused by so called ''afterdepolarizations'' (early or delayed afterdepolarisations EADs / DADs) caused by electrical instability in the myocardial cell membrane. A typical example of this is [[Torsade de Pointes]].
