Disruption of ventricular activation by subthreshold delayed afterdepolarizations in RyR2-R420Q catecholaminergic polymorphic ventricular tachycardia
{{output}}
Background: Catecholaminergic polymorphic ventricular tachycardia (CPVT) carries increased risk of ventricular arrhythmias due to altered Ca2+ regulation associated with mutations in the ryanodine receptor (RyR2). Increased Ca2+ ... ...
