68例变异型心绞痛动态心电图分析

Eynamic Electrocardiogram Analysis of Anomaly Angina Pectoris

目的分析变异型心绞痛患者的动态心电图的临床特点。方法对68例变异型心绞痛患者,在应用常规心电图进行12导联心电图检查的同时,应用动态心电图采用CB-1300动态心电记录仪全信息记录,对两种方法进行比较,同时应用动态心电图分析心绞痛发作次数和时间。结果动态心电图在ST段抬高、T波高耸室性、心律失常、U波倒置、房性传导阻滞和R波增高S段降低上,与常规心电图组比较,差异均有统计学意义(P<0.05)。变异型心绞痛总共发作128次,其中凌晨(2:00～6:00)56例(43.75%)、夜里(22:00～2:00)32例(25.00%)、上午(6:00～10:00)24例(18.75%)为主要发病时间,以凌晨发作次数最多;中午(10:00～14:00)和下午(14:00～18:00)相对较少,各占2例(1.56%)和3例(2.34%)。每次发作的平均时间以凌晨最长,依次是夜里、上午、晚上、下午和中午。结果DCG监测时间长、信息量大,能准确完整记录到变异型心绞痛发作的全过程,有重要的临床价值。

OBJECTIVE Analysis of variant angina patients with clinical characteristics of dynamic electrocardiogram. METHODS 68 cases of patients with variant angina pectoris, ECG Cardio Max-FX-3010 models used ECG 12 lead ECG to check the application of dynamic electrocardiogram while suing CB-1300 Model-wide information recording devices to compare the two methods, while the application of dynamic electrocardiogram analysis angina pectoris time. RESULTS Dynamic electrocardiogram in St-segment elevation, T wave of high-rise room, arrhythmia, U wave inversion, atrial conduction block and the R wave to reduce the higher S, and ECG group, have significant difference （P〈0.05）. Variant angina attack a total of 128 times, including the early morning （2：00-6：00） 56 times （43.75%）, the night （22：00-2：00） 32 cases （25.00%）, morning （6：00-10：00） 24 cases （18.75%） as the majorincidence of time to the early morning attack at the most; noon （10：00-14：00） and afternoon （14：00-18：00） realtively small, each 2 eases （1.56%） and 3 cases （2.34%） . The average time for each attack to the early morning of the longest, followed by night, and at noon. CONCLUSIONS DCG monitoring long and informative, can accurately complete record to variant angina attack the whole process has important clinical value.
