Gap junctions: functional effects of molecular structure and tissue distribution.

Abstract excerpt

Abnormal conduction is fundamental to the pathogenesis of both atrial fibrillation and ventricular tachycardia/fibrillation. Normal atrial and ventricular myocytes express different combinations of multiple gap junction channel proteins and are interconnected by gap junctions in markedly different spatial distributions. These observations suggest that the disparate anisotropic conduction properties of atrial and...
