Traditionally categorized as either functional (e.g., catecholaminergic polymorphic ventricular tachycardia, CPVT) or structural (e.g., arrhythmogenic cardiomyopathy, ACM), these syndromes are increasingly recognized to share a common reliance on neurocardiac signaling. In this review, we examine CPVT and ACM as representative extremes of the functional-structural continuum, highlighting how sympathetic activation acts not only as an acute arrhythmic trigger but also as a chronic driver of disease progression. We dissect the roles of \u03b2-adrenergic signaling, neuropeptide Y (NPY), and regional innervation patterns in shaping myocardial excitability, remodeling, and arrhythmogenesis. While CPVT exemplifies a trigger-dependent, Ca<jats:sup>2+<\/jats:sup>-driven arrhythmia in structurally normal hearts, ACM demonstrates a substrate-amplified phenotype involving maladaptive autonomic remodeling and neurogenic fibrofatty infiltration. We discuss the emerging relevance of neuromodulatory and peptidergic therapies\u2014including \u03b2-blockade, left cardiac sympathetic denervation, and NPY antagonism\u2014and propose an integrated framework for arrhythmia classification and management based on autonomic mechanisms. By reframing inherited arrhythmias as disorders of integrated neural and myocardial physiology, we highlight new opportunities for mechanistic insight, biomarker development, patient stratification, and translational therapy.
