Dr. Sarvazyan laboratory explores cellular mechanisms of ectopic arrhythmias. It focuses on a newly discovered condition called ectopic nexus. It refers to a functional state of an injured cardiac tissue in which multiple poorly-coupled ectopic sources form a transient breeding microenvironment in which ectopic activity develops from individual cells into slowly propagating ectopic waves confined to the area of injury. Dr. Sarvazyan's group is also interested the impulse propagation and excitability properties of the cardiomyocyte networks derived from stems cells.
