Intracoronary beta-irradiation with a liquid (188)re-filled balloon: six-month results from a clinical safety and feasibility study.

abstract：:All of the electrophysiological mechanisms of arrhythmias are sensitive to the influences of the autonomic nervous system, particularly to its adrenergic limb. Arrhythmogenic areas may also be dependent on the inhomogeneity of these influences because of their pathophysiological structure and/or the neurogenic or humo...
