Hypertonicity increases rabbit atrium and pulmonary vein arrhythmogenesis: a potential contributor to the genesis of atrial fibrillation.

abstract：:1. The concentration of methylguanidine and guanidinosuccinic acid has been measured in normal human plasma and discrepancies between various published methods for measuring methylguanidine have been resolved. Previous methods have been modified to allow these guanidines, together with guanidinoacetic acid and creatin...
