Electrocardiogram (ECG) is considered the most used diagnostic tool to identify many cardiological disease and conditions that require the monitoring and recording of heart's electric activity. The aim of this study is the validation and application of a web-survey, addressed to nursing students and nurses, in order to evaluate the degree of accuracy and the knowledge on the correct positioning of the 12-leads ECG.
The study was a cross-sectional questionnaire-based study. The survey comprised 30 items, mainly multiple-choice questions. The participants were 484 nurses and nursing students. In the study, no exclusion criteria were adopted, but fill in the questionnaire any nurse on duty during the data collection period and/or any nursing student during the data collection period. Statistical analyses were performed using the SAS v. 9.4. In the study, no exclusion criteria were adopted.
A total of 484 nursing students and nurses comprising of 149 males (30.79%) and 335 females (69.21%) responded. In full findings showed good psychometric properties and good reliability. The Cronbach's alpha coefficient for the study is 0.76 (number of items = 17, number of obs= 484). The mean age of responders was 32.01 (Standard deviation (SD) 9.63). A logistic multivariate regression demonstrated significant differences.
It is evident from our findings and those from other countries, that more education is required to ensure that mistaken interpretation, misdiagnosis, patient mismanagement and/or inappropriate procedures due to 12 leads ECG misplacement does not occur.
心电图（ECG）被认为是最常用的诊断工具，可用于识别许多需要监测和记录心脏电活动的心脏疾病和病症。本研究的目的是验证和应用一项针对护理学生和护士的网络调查，以评估 12 导联心电图正确定位的准确性和知识程度。
这是一项横断面基于问卷调查的研究。该调查包括 30 个项目，主要是多项选择题。参与者为 484 名护士和护理学生。在研究中，没有采用排除标准，但在数据收集期间，任何值班护士和/或任何护理学生都可以填写问卷。统计分析使用 SAS v. 9.4 进行。在研究中，没有采用排除标准。
共有 484 名护理学生和护士参与了调查，其中包括 149 名男性（30.79%）和 335 名女性（69.21%）。总体调查结果显示出良好的心理测量学特性和良好的可靠性。该研究的克朗巴赫α系数为 0.76（项目数=17，观察数=484）。应答者的平均年龄为 32.01（标准差（SD）9.63）。逻辑多元回归显示存在显著差异。
从我们的研究结果和其他国家的研究结果可以明显看出，需要进行更多的教育，以确保不会因 12 导联心电图放置错误而导致错误解释、误诊、患者管理不当和/或不当程序。
