Left ventricular length dependent activation in the isovolumetric rat heart.

abstract：AIMS:Catecholaminergic polymorphic ventricular tachycardia type 1 (CPVT1) is caused by mutations in the cardiac ryanodine receptor (RyR2) that lead to disrupted Ca(2+) handling in cardiomyocytes and ventricular tachycardia.
