从3200次24小时动态心电图(AECG)记录中,发现10例由房室结双径路引起的1°与2°房室阻滞(A-VB)。其中男性8例,女性2例,平均年龄35±22岁。2例患冠心病,1例二尖瓣脱垂,另7例无心脏病证据。在常规心电图上5例呈“阵发性”A-VB(1°3例,2°I型2例),另5例正常,因心悸或眩晕而进行AECG检查。 10例皆在AECG上有下列一或多项特征:1.P-R间期突然延长,至少持续3个心动周期;2.在长P-R间期周期后,P-R间期突然正常化;3.呈不典型的文克白序列,在P波被阻滞之前任何一个P-R间期突然延长>0.10s。这些病人
From 3200 24-hour Holter AECG recordings, 10 were found to have 1 ° and 2 ° atrioventricular block (A-VB) due to atrioventricular node dual pathway. Including 8 males and 2 females, with an average age of 35 ± 22 years. 2 cases of coronary heart disease, 1 case of mitral valve prolapse, and the other 7 cases of no evidence of heart disease. In conventional ECG 5 cases were “paroxysmal” A-VB (1 ° 3 cases, 2 ° I 2 cases), and the other 5 cases of normal, due to palpitations or dizziness and AECG examination. All of the 10 patients had one or more of the following characteristics on the AECG: 1. Sudden prolongation of the PR interval for at least 3 cardiac cycles; 2. PR interval normalization suddenly after the long PR interval; 3. No A typical vancomycin sequence suddenly prolongs any PR interval> 0.10s before the P wave is blocked. These patients
