插入性室早,临床十分常见,但由于干扰和隐匿性传导的存在,使室早后的第一个窦性搏动的P-R间期延长,第二个窦性搏动及时出现,因而形成短的R-R间期,此种情况易被心电图的初学者误诊为房性早搏,现报告1例如下。心电图cm1,cm5,导联连续记录中可见窦性P波顺序出现,除插入性室早后的两个窦性下传的 Intermittent ventricular early and clinical is very common, but because of the interference and occult conduction exists, so that the early ventricular sinus beats the first PR interval prolongation, the second sinus beats appear in time, resulting in a short RR Interphase, this situation is easy to be misdiagnosed as atrial premature beats ECG, now report a case as follows. Electrocardiogram cm1, cm5, continuous recording of the lead can be seen in sinusoidal P wave sequence, in addition to the insertion of two sinus sinuses early
