1. Rate dependence of action potential is a fundamental property of cardiac cells . 2. Other tests showed an improvement in cardiac cell contractile function by inhibiting G ??. 3. Chloride channel activity in epethelial and cardiac cells has been found to be G protein-dependent. 4. The cardiac cells of the sinoatrial node provide the pacemaker potential that synchronizes the heart. 5. Without this negative resting potential, cardiac cells cannot repolarize ( prepare for their next contraction ). 6. This supports the notion that the protective ingredient in dietary fish dampens electrical instability in cardiac cells . 7. In non-cardiac cells , blocking I kr has a different effect : it increases the frequency of action potentials. 8. His research includes cardiac cell biology and tissue engineering, traumatic brain injury, and biological applications of micro-and nanotechnologies. 9. Reardon said heart malignancy is very rare because most cancers occur in cells that replace themselves regularly, unlike cardiac cells . 10. Heart malignancy is extremely rare, Reardon said, because most cancers happen in cells which replace themselves regularly, unlike cardiac cells .
