Sinus node dysfunction following targeted disruption of the murine cardiac sodium channel gene Scn5a

, 2005
We have examined sino-atrial node (SAN) function in hearts from adult mice with heterozygous targeted disruption of the Scn5a gene to clarify the role of Scn5a-encoded cardiac Na+ channels in normal SAN function and the mechanism(s) by which reduced Na ...
