Abstract:
Review concerns modern views on ionic mechanism of action potential formation in cardiomyocytes. Main characteristics of cardiomyocyte ion current are described. Importance of ion current in formation of action potential phases in various regions of the heart is considered. Molecular structure and up-to-date classification of ion channels are presented. Number of genetic abnormalities which lead to appearance of arrhythmias are described.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

Voltage-gated Ion Channels
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several types of...
