The mechanisms by which spontaneous electrical activity originates in the ischemic heart and leads to arrhythmia remain unknown, however mechanical stretch of the diseased region has been hypothesized to play a role. The goal of this study is to investigate the conditions that favor the initiation of stretch-induced premature beats in the ischemic heart. We employ a mathematical model of the ischemic cell subjected to stretch. The study found that upon stretch, spontaneous beats occur in the ischemic cell, which are due to the stretch-induced re-activation of the L-type calcium current.
