精神障碍患者心电图QRS波低电压异常情况及影响因素分析

目的 探究精神障碍患者心电图QRS波低电压异常情况及影响因素。方法 选取精神障碍患者300例作为研究对象，统计其一般资料及心电图QRS波低电压异常情况，分析精神障碍患者心电图QRS波低电压异常的影响因素。结果 300例精神障碍患者心电图QRS波低电压异常120例(40.00%),其中肢导联QRS波低电压65例(54.17%)、胸导联QRS波低电压45例(37.50%)、全导联QRS波低电压10例(8.33%)。120例心电图QRS波低电压异常患者均伴有不同异常心电图变化，如窦性心动过速、窦性心律不齐、窦性心动过缓、期前收缩、不完全性右束支阻滞、T波改变、ST段改变、Q-T间期延长、左心室高电压等，可单一表现或多种共存。病程、年龄、用药时间、剂量指数、抗精神病类药物均是精神障碍患者心电图QRS波低电压异常的影响因素(P<0.05)。结论 精神障碍患者心电图QRS波低电压异常高达40.00%,年龄、病程、用药时间、剂量指数、抗精神病类药物是精神障碍患者心电图QRS波低电压异常的影响因素。

Analysis of abnormalities of low QRS voltage in electrocardiogram of patients with mental disorders and its influencing factors

Objective To investigate the abnormalities of low QRS voltage (LQRSV)inelectrocardiogram (ECG) in patients with mental disorders and the influencing factors.Methods In total, 300 patients with mental disorders were selected as the research subjects, and their general data and abnormalities of LQRSV in ECG were collected to analyze the influencing factors of LQRSV abnormalities in ECG in patients with mental disorders.Results Of 300 patients with mental disorders, there were 120 cases (40.00%) of abnormal QRS voltage in ECG, including 65 cases (54.17%) of LQRSV in limb leads, 45 cases (37.50%) of LQRSV in chest leads, and 10 cases (8.33%) of LQRSV infull leads.All 120 patients with LQRSV abnormalities in ECG were accompanied by different abnormal ECG changes, such as sinus tachycardia, sinus arrhythmia, sinus bradycardia, preterm contraction, incomplete right bundle branch block, T-wave changes, ST-segment changes, Q-T interval prolongation, and left ventricular hypervoltage, which could be single or multiple manifestations. Duration of illness, age, duration of medication, dose index, and antipsychotics were all influencing factors for abnormal LQRSV in ECG in patients with mental disorders (P＜0.05).Conclusion Abnormal LQRSV in ECG in patients with mental disorders is as high as 40.00%, and age, duration of illness, duration of medication, dose index, and antipsychotics are the influencing factors of abnormal LQRSV in ECG in patients with mental disorders.
