Adaptability in precordial lead placement is one of the sources of electrocardiography inaccuracy. The present experimental study aimed to investigate the modified precordial lead ECG SafOne on electrocardiography recordings. Fourteen subjects were selected using purposive sampling. All the artefacts that emerged in the ECG recording results from the subjects using both the modified precordial lead ECG SafOne and precordial lead standard ECG were measured and identified. Data were analysed using a t test to examine the difference in the artefacts from all ECG recordings. The electrocardiography recordings of males aged 21-25 years using modified precordial lead ECG SafOne showed that out of 168 precordial leads from 14 subjects, two indicated artefact images in lead II (1.19%) and three in lead III (1.79%). The statistical test showed no significant difference in terms of artefacts that emerged in the electrocardiography recording results from both standard ECG and modified precordial lead ECG SafOne (p = 0.096). The modified precordial lead ECG SafOne showed no significant effect on ECG recordings related to artefacts. Additionally, the precordial lead ECG SafOne had no substantial difference in the presence of artefacts compared to the standard ECG. Therefore, ECG SafOne was usable as an ECG precordial lead for electrocardiography recording.
胸前导联位置的适应性是心电图不准确的原因之一。本实验研究旨在探讨改良胸前导联心电图 SafOne 对心电图记录的影响。采用目的抽样法选取了 14 名受试者。测量并识别了受试者使用改良胸前导联心电图 SafOne 和标准胸前导联心电图得出的所有心电图记录结果中的所有伪影。使用 t 检验分析数据,以检查所有心电图记录中伪影的差异。使用改良胸前导联心电图 SafOne 对 21-25 岁男性进行的心电图记录显示,在 14 名受试者的 168 个胸前导联中,有两个导联 II(1.19%)和三个导联 III(1.79%)出现伪影图像。统计检验显示,标准心电图和改良胸前导联心电图 SafOne 的心电图记录结果中出现的伪影无显著差异(p=0.096)。改良胸前导联心电图 SafOne 对心电图记录中的伪影无显著影响。此外,与标准心电图相比,胸前导联心电图 SafOne 存在伪影的情况没有实质性差异。因此,心电图 SafOne 可作为心电图胸前导联用于心电图记录。
