Discussion
An injectable carbon nanotube hydrogel was developed by our group with enhanced conductive properties that retain conductivity in aqueous environments. Furthermore, we have demonstrated that injection of such a hydrogel into iatrogenic regions of myocardial injury can enhance conduction through these regions. These data provide support that such a conductive material may impact conduction characteristics of myocardium. They also lay the foundation for future work to enhance understanding of the utility of such an approach and the potential impact on arrhythmogenesis.
