An isolated cardiac conduction disease maps to chromosome 19q.

abstract：:Inducible nitric oxide synthase (iNOS) protein is expressed in cardiac myocytes of patients and experimental animals with congestive heart failure (CHF). Here we show that iNOS expression plays a role in pressure overload-induced myocardial chamber dilation and hypertrophy. In wild-type mice, chronic transverse aortic...
