摘要/Abstract

摘要： 目的探讨动态心电图P波特征与急性心肌梗死(AMI)患者新发房颤(NOAF)(AMI-NOAF)的关系。方法选取甘肃省武威肿瘤医院收治的240例AMI患者,均进行动态心电图检查,收集患者动态心电图P波特征参数及临床资料,分析P波特征与AMI患者临床参数的关系。根据是否发生NOAF分为NOAF组和未发生(non-NOAF)组,采用多因素Logistic回归模型分析AMI发生NOAF的影响因素。结果 Killip Ⅲ~Ⅳ级最小P波时限(P_min)水平低于Ⅰ~Ⅱ级,最大P波时限(P_max)、P波离散度(Pd)水平高于Ⅰ~Ⅱ级(P＜0.05);240例AMI患者中47例发生NOAF,发生率为19.58%;NOAF组P_min水平低于未发生组,P_max、Pd水平高于未发生组(P＜0.05);NOAF组入院时心率及Killip Ⅲ~Ⅳ级占比高于未发生组(P＜0.05);多因素Logistic回归分析结果显示,Killip Ⅲ~Ⅳ级、P_max、Pd高水平是影响AMI发生NOAF的独立危险因素(P＜0.05)。结论 P_min、P_max、Pd水平与AMI患者Killip分级有关;AMI-NOAF患者动态心电图P波特征异常,其中高水平P_max、Pd是影响AMI发生NOAF发生的独立危险因素。

Abstract: Objective To investigate the relationship between dynamic electrocardiogram P-wave sign and new-onset atrial fibrillation (NOAF) in patients with acute myocardial infarction (AMI)(AMI-NOAF). Methods Totally 240 patients with AMI admitted to Wuwei Cancer Hospital were examined by dynamic electrocardiogram. P-wave sign parameters and clinical data of holter electrocardiogram were collected. The relationship between P-wave sign and clinical parameters of AMI patients was analyzed. The patients were divided into NOAF group and nonoccurrence(non-NOAF) group and multivariate Logistic regression model was used to identify the influencing factors of NOAF occurrence in AMI. Results Killip Ⅲ-Ⅳ grade minimum P wave duration (P_min) level was shorter than that of Ⅰ-Ⅱ grade. Maximum P wave duration (P_max) and P wave dispersion (Pd) level were higher than that of Ⅰ-Ⅱ grade(P＜0.05). NOAF occurred in 47 of 240 AMI patients (19.58%). The level of P_min in NOAF group was lower than that in non-NOAF group, and the level of P_max and Pd in NOAF group was higher than that in non-NOAF group(P＜0.05). The heart rate and the proportion of Killip grade Ⅲ-Ⅳ in NOAF group were higher than those in non-NOAF group(P＜0.05). Multivariate Logistic regression analysis showed that Killip Ⅲ-Ⅳgrade, high level of P_max and Pd were independent risk factors for NOAF in AMI (P＜0.05). Conclusions The level of P_min, P_max and Pd are correlated with Killip grading in AMI patients. AMI-NOAF patients have abnormal P-wave sign in holter electrocardiogram. The high levels of P_max and Pd are independent risk factors of AMI and NOAF.
