目的分析动态心电图对室性心动过速中的监测意义。方法回顾分析75例患者的临床资料。结果75例患者共检出PVT2280阵,其中24h内发生1阵35例,2～10阵25例,10阵以上5例。每例发作1～225阵次,发作持续时间0.82～26s,每阵3～32次搏动,联律间期0.40～0.82s。本组室速发作时心室率150～160次/min42例,160～170次/min23例,170～180次/min10例。DCG显示,大部分患者合并有其他心律失常,属多源PVS45例,单源PVS30例,多形性室性心动过速52例、单形性室性心动过速23例。本组75例基础心律全部为窦性,其中伴有PVS52例、成对出现PVS30例、PVS呈二、三联律22例;经治疗后好转出院,全部病例在治疗期间无1例发展为持续性室性心动过速、心室颤动或死亡。结论有器质性心脏病,心功能失代偿,血流动力学不稳定者,室性心律失常是高危因素;故对室性心律失常应结合临床资料,充分认识高危患者,客观评价其预后。
Objective To analyze the significance of Holter monitoring in ventricular tachycardia. Methods The clinical data of 75 patients were retrospectively analyzed. Results 75 patients were detected PVT2280 array, including a case of 35 cases in 24 hours, 2 to 10 array 25 cases, 10 more than 5 cases. Each episode of 1 to 225 array, episode duration 0.82 ~ 26s, each beat 3 to 32 beats, joint law interval 0.40 ~ 0.82s. Ventricular rate of this group VT onset of ventricular rate of 150 to 160 beats / min42 cases, 160 to 170 beats / min23 cases, 170 to180 beats / min10 cases. DCG showed that most patients with other arrhythmias, is a multi-source PVS45 cases, 30 cases of single source PVS, pleomorphic ventricular tachycardia in 52 cases, monomorphic ventricular tachycardia in 23 cases. The 75 cases of basic rhythm in this group of sinus, including PVS52 cases, PVS30 cases in pairs, PVS was two, triple the law in 22 cases; after treatment and better discharge, all cases in the treatment period, no one developed to persistent Ventricular tachycardia, ventricular fibrillation or death. Conclusion There are organic heart disease, cardiac decompensation, hemodynamic instability, ventricular arrhythmias are risk factors; Therefore, ventricular arrhythmia should be combined with clinical data, fully understand the high-risk patients, an objective evaluation of their prognosis .
