Electrical coupling between ventricular myocytes and myofibroblasts in the infarcted mouse heart [PDF]

open access: yes, 2017
Aims: Recent studies have demonstrated electrotonic coupling between scar tissue and the surrounding myocardium in cryoinjured hearts. However, the electrical dynamics occurring at the myocyte-nonmyocyte interface in the fibrotic heart remain ...
