应用高分辨叠加心电图检测30例正常人、100例冠心病人、50例冠心病合并频发室早病人、26例冠心病合并室速病人的整个 QRS 波群及 S-T 段,分析四组人心室碎裂电位的检出率。结果显示:在三组病人中可记录到心室不同时期的碎裂电位,以冠心病合并室速者最为多见。结果提示:重视 QRS 早期改变及观察整个 QRS 对识别此类患者具有室速和猝死高危者有重要意义。
High resolution overlay electrocardiogram was used to detect 30 normal subjects, 100 coronary heart disease patients, 50 patients with coronary heart disease complicated by frequent ventricular anomalies, 26 patients with coronary heart disease with ventricular tachycardia in the entire QRS wave group and ST segment, The detection rate of fragmentation potential. The results showed that in three groups of patients can be recorded at different times of the ventricular fibrillation potential, the most common coronary heart disease with ventricular tachycardia. The results suggest that: the importance of early changes in QRS and observation of the entire QRS to identify such patients have a high risk of ventricular tachycardia and sudden death are of great significance.
