目的探讨128例高级别室早的动态心电图特征及其临床意义。方法对128例高级别室早及其临床资料进行回顾性分析。并按照Lown分级法进行分类。结果Ⅳa 78例,Ⅳb 41例,RonT 9例。结论高级别室早都出现在有器质性心脏病变患者,并发生于频发多源室早及单发次数室早较多的患者,高级别室早属于恶性心律失常是诱发心脏猝死的主要原因,应引起临床足够重视给予积极治疗。
Objective To investigate the characteristics and clinical significance of ambulatory electrocardiogram (ECG) in 128 cases of high-grade room. Methods A retrospective analysis of 128 cases of high-grade room early and clinical data. And in accordance with the classification of Lown classification. Results 78 cases of IVa, 41 cases of IVb, 9 cases of RonT. CONCLUSIONS: High-grade patients have been present in patients with organic heart disease for many years, and occur frequently in patients with frequent multi-source ventricular premature ventricular and single-frequency premature ventricular failure. Malignant arrhythmias in high-grade patients are the major causes of sudden cardiac death Reason, should cause enough attention to give clinical active treatment.
