Derived 12-lead electrocardiogram in the assessment of ST-segment deviation and cardiac rhythm

A comparison between EASI system 12‐lead ECGs and standard 12‐lead ECGs for improved clinical nursing practice

“…Previous studies showed that there are very few changes between the two lead methods in cardiac intervals measurement (PR interval, QRS duration) and that there is more variation in P, QRS and T‐wave axes (Drew et al. 1999, Chantad et al. 2006).…”

“…Although the conventional 12‐lead ECG is the current diagnostic standard in ST segment analysis and cardiac arrhythmias detection, it is impractical for continuous monitoring in CCUs because it requires a large number of electrodes and, therefore, it would determine discomfort to patients, interference with medical procedures and susceptibility to motion artifacts (Chantad et al. 2006).…”

Electrode positions, transformation coordinates for ECG reconstruction from S-ICD vectors

“…The quantitative measures of similarity between the original (measured) ECG and the corresponding derived (reconstructed) ECG were determined using Pearson r correlation [2], [3] and root mean square error (RMSE) analysis [3], [4] for each derived lead. The Pearson r was considered to show high positive correlation [5] at r ≥0.7.…”

Accuracy of EASI 12‐lead ECGs in monitoring ST‐segment and J‐point by nurses in the Coronary Care Units

“…Continuous monitoring with a standard 12‐lead ECG is impractical in CCUs because this type of ECG requires a large number of electrodes (10), and, therefore, it could be discomfortable for the patients and susceptibility to artifacts due to motion (Chantad et al . ). For these reasons, continuous ECG monitoring systems that use a reduced number of electrodes (Reduced Leads System – RLSS) have been implemented over time (Nelwan et al .…”
