MiRP1 forms IKr potassium channels with HERG and is associated with cardiac arrhythmia. [PDF]
A novel potassium channel gene has been cloned, characterized, and associated with cardiac arrhythmia. The gene encodes MinK-related peptide 1 (MiRP1), a small integral membrane subunit that assembles with HERG, a pore-forming protein, to alter its ...

A KATP channel opener inhibited myocardial reperfusion action potential shortening and arrhythmias [PDF]
Low concentrations of certain K<sub>ATP</sub> channel openers have been reported to exert a moderate inhibitory effect on arrhythmias during post-ischaemic early myocardial reperfusion, but the accompanying effects on the time course of ...
