心脏起搏已成为颈动脉窦过敏引起昏厥患者的首选治疗方法.颈动脉窦按摩约在80%患者中主要引起心脏抑制反应.在5～10%患者仅引起血管抑制反应;不少患者既引起心脏抑制又引起血管抑制反应,对这些混合性反应患者,由于心室起搏不能纠正血管抑制反应,症状可持续存在.本文报道一组用起搏治疗的颈动脉窦综合征患者,并分析起搏后症状持续的原因.
Cardiac pacing has become the preferred treatment for patients with syncope caused by carotid sinus anaphylaxis. Carotid sinus massage primarily causes cardiac inhibition in about 80% of patients, causing vasorelaxation only in 5% to 10% of patients, and in many patients Cardiac suppression in turn leads to vasorelaxant responses, and in these mixed response patients, the symptoms persist due to the fact that ventricular pacing can not correct the vasorelaxation response.This article reports a group of patients with carotid sinus syndrome treated with pacing and analyzes pacing After the symptoms persist.
