Using Tissue Phase Mapping, we investigated the influence of IKr-blocking drug E4031 on global and segmental mechanical cardiac function in transgenic LQT type 1 rabbits (loss of IKs, with a particularly high susceptibility to IKr-blocking drugs) and wild-type littermate controls.enconference paper
