Dynamic action potential clamp studies of drugs that affect the cardiac action potential

The development of drugs to treat and.or prevent cardiac arrhythmias have been plagued by the side-effect of actually increasing the risk of sudden death. One of the reasons for this is that drugs that work well in one part of the heart may cause problems in another part. We are developing a system called “dynamic action potential clamp” that will make it easier for researchers to assess the effect of drugs in different regions of both normal and diseased hearts.
