However, errors in the placement of precordial leads, misplacement, and interchange of precordial electrodes will cause invalid ECG recordings 13. This diagnostic test (ECG) is important to record the electrical activities of the heart that can be recorded using electrodes attached to the six thoracic bones and four extremity landmarks. The difference between these two tools is in the utility, where Tsukada’s smart garment is usable for continuous and repeated ECG monitoring, not during dynamic trunk movement, while Li’s smart clothing showed good recording performance in the conditions of sleeping and jogging 6, 12. Electrode textile pads and lead wires were sewn to a textile that tolerated repeated washings and collected ECG signals during recording. Both studies aimed to investigate the usefulness of textile electrodes for ECG recording using fabric as the material. (2019) and Li, Xiong and Li (2020) developed a measurement of ECG signals based on textile material called the wearable measurement of ECG 6, 12. On contrast, ECG SafOne can only be applied to males with two different sizes of device (medium and large) based on the Indonesian male standard size, and it is not designed for long-term use during the procedure. CQP can be applied to both males and females of all torso sizes and stay on the patient for up to three days. Thus, ECG SafOne is easy and practical in terms of finding the V1–V6 placement, and it is time efficient. The CQP uses adaptable horizontal placement and rigid vertical placement designs, which still need time to ensure electrode position when used, while ECG SafOne uses a single simple design. CPQ and ECG SafOne use different designs, materials and procedures. Similar to ECG SafOne, the CQP aimed to improve the accuracy of electrode placement that can be applied in a time that is comparable to single-electrode application. (2016) developed the CardioQuick Patch (CQP) to assist operators in accurately positioning electrodes during 12-lead ECG acquisition 11. The rapid development of technology has a significant impact on new technology, including in the health sector. These 12-lead ECGs have recently become the topic of an important and interesting investigation around the globe since their introduction into clinical practice 10. An excellent standard is the well-known 12-lead ECG, where wires are connected to electrodes placed on 10 locations on the body 7, 9. Since then, a wide range of ECG devices have been used in clinical practice: 12-lead ECG, multichannel ECG (MECG), Holter monitoring, implantable loop recorder (ILR), and others 6, 7, 8. This method for electrocardiography recording was invented in the 1930s and established in clinical practice in the 1940s and is currently known as a 12-lead electrocardiogram (ECG) 5. This diagnostic tool works with an ECG signal recorded from many electrodes attached over the skin to detect and diagnose cardiac disease 3, 4. Therefore, ECG SafOne was usable as an ECG precordial lead for electrocardiography recording.Įlectrocardiography (ECG or EKG) recording is one of the most important cardiac diagnostic tests because it is used to determine cardiac problems and is noninvasive, inexpensi 1, 2. Additionally, the precordial lead ECG SafOne had no substantial difference in the presence of artefacts compared to the standard ECG. The modified precordial lead ECG SafOne showed no significant effect on ECG recordings related to artefacts. 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 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%). Data were analysed using a t test to examine the difference in the artefacts from all ECG recordings. 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. Fourteen subjects were selected using purposive sampling. The present experimental study aimed to investigate the modified precordial lead ECG SafOne on electrocardiography recordings. Adaptability in precordial lead placement is one of the sources of electrocardiography inaccuracy.
