As a result of our literature review, we adjusted previous stimulation protocols in attempt to facilitate reproducible VA induction in wildtype mice with a defined protocol. WebDec 18, 2024 · To further study the effect of abnormal CaMKII at higher heart rates, the widely used burst pacing protocol was applied to induce abnormal cell behaviors. The cell model was first initialized with 1-Hz pacing, then stimulated at 10 Hz for 12 s (burst pacing period). Finally, we resumed the stimulation frequency to 1 Hz to see how myocytes react.
