Optogenetic termination of ventricular arrhythmias in the whole heart: towards biological cardiac rhythm management

Abstract

Brief local epicardial illumination of the optogenetically modified adult rat heart allows contact- and shock-free termination of ventricular arrhythmias in an effective and repetitive manner after optogenetic modification. These findings could lay the basis for the development of fundamentally new and biological options for cardiac arrhythmia management.
