目的分析特发性室性心动过速(室速)伴发心律失常的临床特点和体表心电图特征,以及药物终止心动过速中出现的心律失常特征.方法收集特发性室性心动过速16例患者的临床资料进行回顾性分析,并对典型患者的临床特点和心电图资料结合文献进行分析.结果 16例患者中右心室室速6例,左心室室速8例,左心室游离后壁近心尖部2例.室性心动过速的心电图特点:室速发作的频率为125～250次/min,波动范围较大,右心室流出道室速额面QRS波平均心电轴为+(81.86±26.08)°,左心室后间隔室速额面QRS波平均心电轴为-(89.25±40.37)°.特发性室性心动过速可伴发窦性和房性心律失常,在应用药物终止心动过速时可出现窦房抑制,继而出现逸搏,逸搏心律,心房扑动和逸搏反复搏动各1例,3例有电张调整性T波改变.结论特发性室速伴其他心律失常虽较少见,但在药物终止过程中可出现一过性心律失常,应重视心电监护并及时描记心电图,并及时做相应处理.

Objective To analyze clinical characteristic, electrocardiogram (ECG) changes of idiopathic left ventricular tachycardia (ILVT) and cardiac arrhythmia during anti-arrhythmia treatment. Methods All 16 ILVT patients were included in the study. Clinical and ECG data of 6 patients were analyzed and a systemic review was made with previous studies. Results Sinus and auricular arrhythmia were detected. Sinus node dysfunction,functional escape and escape rate were detected during anti-arrhythmia treatment. However, auricular tachycardia,recurrent escape beat were rarely observed. Nonspecific T wave changes were investigated during treatment.Conclusions Arrhythmia with ILVT is rarely observed. However transient arrhythmia can be seen during treatment. Accordingly ECG monitoring and timely treatment are important for therapy of ILVT.
