摘　　要：目的:探讨各种类型“诊断性室性早搏”,即有Q波的室性早搏的产生机理及其与临床疾病的关系。方法:对12导联同步分析心电图及12导联动态心电图中选取符合有Q波的室性早搏的图例95例分为A、B、C三型,分析其起源、产生机理及病因。结果:有Q波的室性早搏72%起源于左室,28%起源于右室。这三种类型的有Q波的室性早搏的形态改变与心肌梗死无明显关系,甚至与器质性心脏疾病的关系不大。结论:有Q波的室性早搏对心肌梗死的诊断价值十分有限,个别伴有ST段弓背抬高的室性早搏提示心肌梗死时需密切结合临床。Objective： To explore the mechanism and clinical significance by all kinds of ＂diagnostic ventricular premature beat＂ namely ventricular premature beat（PVC） with Q wave. Methods： 95 cases were chose from synchronous 12-lead electrocardiogram and 12-lead dynamic electrocardiogram recording during daily-work, and they were divided into three groups, analysis it＇s origin,mechanism and cause of disease. Results： PVCS with Q wave originated from left ventricular in 68 patients （72%）, and originated from right ventricular in 27 patients （28%）. The ECG change of this PVCS with Q wave has no correlation apparent to the myocardial infarction （4/95）, even to the organic heart diseases （8/95）. Conclusion： It isn＇t very value that using ventricular premature beat with Q wave to diagnostic myocardial infarction, it must be combined to clinical closely when we diagnose myocardial infarction using ventricular premature with arched ST segment elevation.
