영구성 심박동 조율기(DDD) 로 치료한 과민성 경동맥동 증후군 1 예

The major clinical manifestation of carotid sinus hypersensitivity syndrome is characterized by syncope or other manifestation of cerebral dysfunction (dizziness, lightness). Three types of carotid sinus hyper~sen- sitivity syndrome have been defined; 1) cardioinhibitory-ventricular asystole occuring for longer 3 seconds; 2) vasodepressor-a decrease in systolic arterial blood pressure of more than 50mmHg (with a less than 30% decrease in heart rate) and 3) mixed-a decrease in systolic arterial blood pressure of more than 30mmHg (with a more than 30% decrease in heart rate). In symptomatic patients with carotid sinus hypersensitivity syndrome associated with significant cardioinhibition, permernent pacemaker implantationhas played an increasingly frequent therapeutic role. In carotid sinus hypersensitivity, VVI pacing mode results in increased patients symptomes because of aggravation of the vasodepressor component, and therefore, DDD (DVI mode) is the optimal pacing mode. In this report, we present a case of carotid sinus hypersensitivity syndrome treated with DDD pacemaker.
