Hypervagotonic sinus node dysfunction (SND) is a form of SND with sinus bradycardia caused by enhanced vagal tone. Indirect proof of hypervagotonia as the mechanism can be inferred from resolution of bradycardia following atropine infusion. In symptomatic patients, pacemaker implantation is recommended. We describe cardioneuroablation as a treatment for hypervagotonic SND.
迷走神经张力亢进型窦房结功能障碍(SND)是一种由迷走神经张力增强引起的伴有窦性心动过缓的SND形式。可通过输注阿托品后心动过缓的缓解来推断迷走神经张力亢进作为其机制的间接证据。对于有症状的患者,建议植入起搏器。我们描述了心脏神经消融术作为迷走神经张力亢进型SND的一种治疗方法。
