目的分析Brugada波的电交替现象。方法回顾性分析存在1型Brugada波且伴ST段和/或T波电交替现象的5例患者的心电图及临床特点。结果 5例患者均为男性,年龄18~50岁,入院时均存在1型Brugada波,并且分别在病因诊断确立或病情得到纠正过程中见到ST段和/或T波的电交替现象。ST段电交替可表现为抬高程度(高和低)的交替和抬高类型的(穹隆型和马鞍型)的交替,T波电交替表现为振幅(高和低)的交替和方向(双向和倒置)的交替。结论 Brugada波电交替现象可以发生于多种情况,同样具有多变性的特点。
Objective To analyze the electric alternating phenomenon of Brugada wave. Methods We retrospectively analyzed the ECG and clinical features of 5 patients who had type 1 Brugada waves accompanied by ST segment and / or T wave alternation. Results All 5 patients were male, aged 18 to 50 years. There was type 1 Brugada wave on admission, and the alternation of ST segment and / or T wave was seen during the diagnosis of etiology or the correction of the disease. The ST segment alternation can be represented by alternation and uplifting (dome and saddle type) alternations of elevation (high and low), alternations of T wave alternans (alternating high and low) and directions (bidirectional And inverted). Conclusion Brugada wave alternating phenomenon can occur in a variety of situations, also has the characteristics of variability.
