Cardiac Ion Channels

The cardiac action potential is the output of multiple ion channels. The cardiac ion channels are a target for cardiac channelopathies often referred to as long QT syndrome (LQTS), but also an important part of any cardiac safety assessment in drugs.

 

Below see selected publications, posters and reports on various ion channel targets performed on QPatch or Qube.
