Excitation-Contraction Coupling between Human Atrial Myocytes with Fibroblasts and Stretch Activated Channel Current: A Simulation Study

Figure 1

Illustration of changes in the waveform of the atrial myocyte AP. (a) 1 myocyte coupled to 𝐼_sac with a λ of 1.1 to 1.3. (b) 1 myocyte coupled to 1 to 3 Fbs with a 𝐺_gap of 1 nS. (c) 1 myocyte coupled to 2 Fbs with a 𝐺_gap of 1 to 3 nS. (d) 1 myocyte coupled to 𝐼_sac or 2 Fbs or 𝐼_sac and Fbs at the same time.
