目的 总结以室性心动过速为首发表现的心脏肿瘤的临床和心电图特点 ,以利及时诊断。 方法 对 1992年 12月～ 1999年 7月收治的 5例以室性心动过速为首发表现 ,后经影像学检查发现并经手术和病理证实的心脏肿瘤患者的临床和心电图特点进行分析。结果 本组 5例均以室性心动过速为首发临床表现 ,心室率 16 0～ 2 0 0次 / m in,其中 ,伴一过性头晕 3例 ,黑 2例。临床无其他症状和体征。既往均无心脏病史 ,而且肿瘤的所在实际部位与心电图所显示的室性期前收缩 ,乃至室性心动过速起源部位基本一致。其中 1例经心内电生理证实。 结论 对临床上以室性心动过速为主要表现的患者 ,应考虑到有心脏肿瘤的可能 ,应行影像学检查确诊。常规心电图所显示的室性心动过速的起源部位对心脏肿瘤有一定的定位价值
Objective To summarize the clinical and electrocardiographic characteristics of cardiac tumors with ventricular tachycardia as the first manifestation to facilitate timely diagnosis. Methods The clinical and electrocardiographic features of 5 patients with cardiac ventricular tachycardia who were admitted to the hospital from December 1992 to July 1999 were determined by imaging findings and confirmed by surgery and pathology. Results 5 cases of this group were all ventricular tachycardia as the first clinical manifestation, ventricular rate 16 0 ~ 200 / m in, of which, with a transient dizziness in 3 cases, 2 cases of black mole. No other clinical signs and symptoms. No previous history of heart disease, and the actual location of the tumor and ECG showed ventricular contraction, and even the origin of ventricular tachycardia is basically consistent. One case was confirmed by intracardiac electrophysiology. Conclusion For patients with clinical manifestations of ventricular tachycardia, the possibility of a heart tumor should be taken into account. Imaging examination should be performed to confirm the diagnosis. The location of the origin of ventricular tachycardia displayed by conventional electrocardiogram has a certain positioning value for heart tumors
