Implication
Hypothesis-generating for IKs-targeted modeling of repolarization failure; requires human studies before any clinical consideration.
Structured PICO
P
Population
Computational Markov model of IKs (slow delayed rectifier K+ current) and its alpha-subunit KCNQ1
I
Intervention
Simulation of kinetic properties during the cardiac ventricular action potential at different rates
O
Outcome
Kinetic properties of IKs and its role in repolarization reservesurrogate
Computational modeling demonstrates that the interaction between KCNQ1 and KCNE1 allows IKs to function as a repolarization reserve, preventing excessive action potential prolongation when IKr is compromised.
