摘　　要：间歇性预激综合征在临床中较为常见,但是其中表现为单个或三联律形式的在临床中较为少见。间歇性预激综合征在心电图中的表现为间歇性的存在及消失,PR间期有时缩短,有时正常。舒张晚期室性期前收缩(室早)在心电图中的表现为联律间期相对较长,形成宽大畸形的QRS波群,T波与主波方向相反。两者根据P-R间期的长短以及"δ"波和舒张晚期中"P"波形态变化进行鉴别。间歇性预激综合征很容易被误诊为舒张晚期室早,两者做出正确诊断将对患者后期临床治疗有重要的意义。Intermittent pre-excitation syndrome is more common in the clinic,but it is less common in the form of single or triplet.Intermittent preexcitation in electrocardiogram showed intermittent existence and disappearance,and PR interval was sometimes shortened and sometimes normal.In the late diastolic phase,the correlation interval was relatively long in electrocardiogram.The T wave of QRS complex with wide deformity is opposite to the direction of main wave.The two were distinguished according to the length of PR interval and the morphological changes of"δ"wave and"P"wave in late diastolic period.Intermittent preexcitation can easily be misdiagnosed as late diastolic ventricular premature beats.The correct diagnosis of the two will be of great significance for the later clinical treatment of patients.
