Animal data on curved strands should not guide clinical stimulation; extends characterization of separable transmembrane responses.
Curved cardiac strands exhibit distinct transmembrane potential responses to electric-field stimulation, characterized by separable passive and active components.
Tung et al. (2000) studied this question. Uniform electric-field stimulation was evaluated on Transmembrane potential (V(m)) responses. Uniform electric-field stimulation of curved cardiac strands produced transmembrane potential responses separable into components with characteristic amplitude, spatial, and temporal signatures.
