ABSTRACT: BACKGROUND: A variety of mutations in HERG, the major subunit of the rapidly activating component of the cardiac delayed rectifier I(Kr), have been found to underlie the congenital Long-QT syndrome, LQT2. LQT2 may give rise to severe arrhythmogenic phenotypes leading to sudden cardiac death. OBJECTIVE: We attempt to elucidate the mechanisms by which heterogeneous LQT2 genotypes can lead to prolongation of the action potential duration (APD) and consequently the QT interval on the ECG. METHODS: We develop Markovian models of wild-type (WT) and mutant I(Kr) channels and incorporate these models into a comprehensive model of the cardiac ventricular cell. RESULTS: Using this virtual transgenic cell model, we describe the effects of HERG mutations on the cardiac ventricular action potential (AP) and provide insight into the mechanism by which each defect results in a net loss of repolarizing current and prolongation of APD. CONCLUSIONS: This study demonstrates which mutations can prolong APD sufficiently to generate early afterdepolarizations (EADs), which may trigger life-threatening arrhythmias. The severity of the phenotype is shown to depend on the specific kinetic changes and how they affect I(Kr) during the time course of the action potential. Clarifying how defects in HERG can lead to impaired cellular electrophysiology can improve our understanding of the link between channel structure and cellular function.

The model for cardiac i_Na includes three closed states (C3, C2 and 
C1) an open, conducting state (O) and fast and slow inactivation 
states (IF and Is, respectively). P_i is the probability of a 
channel occupying a particular state (i), which is determined by a 
system of linear first order differential equations.

In 1999, Viswanathan, Shaw and Rudy published a paper which updated
the original Luo-Rudy II Model. It describes how the slow component
of the time-dependent potassium current has two activation gates,

The use of a Markovian model to represent i_Na deviates from the 
traditional Hodgkin-Huxley approach used in many ionic models 
(including Luo-Rudy II). The Markovian scheme represents distinct 
channel states and coupling between these states, which allowed 
Clancy and Rudy to relate state-specific kinetic properties of ion 
channels to the electophysiological behaviour of the whole cell.
