The interest in mouse electrophysiology is expanding fast, despite the mark
ed differences between mouse and man. Different methods have become availab
le to analyse the electrical activity in the mouse heart in vivo. The mouse
genome can be altered with relative ease, which allows the molecular disse
ction of the various components that contribute to de- and repolarisation o
f the cardiomyocyte and the initiation and propagation of cardiac arrhythmi
as. Mouse ischaemia reperfusion models have been used recently to study pre
ventive measures against ischaemic myocyte damage. In the present review, t
he electrophysiological measurements performed in mice to date are discusse
d and complemented with results from a mouse ischaemia reperfusion model. (
