Does a three-lead patch-type device using an LSTM network accurately reconstruct a standard 12-lead ECG in healthy subjects and patients with pathologic findings?
A three-lead patch-type ECG device using an LSTM network can accurately reconstruct a standard 12-lead ECG, offering a feasible and equivalent alternative to standard 12-lead ECGs.
Effect estimate: Correlation coefficient 0.95
Reconstructing a standard 12-lead electrocardiogram (ECG) from signals received from electrodes packed into a patch-type device is a challenging task in the field of medical instrumentation. All attempts to obtain a clinically valid 12-lead ECG using a patch-type device were not satisfactory. In this study, we designed the hardware for a three-lead patch-type ECG device and employed a long short-term memory (LSTM) network that can overcome the limitations of the linear regression algorithm used for ECG reconstruction. The LSTM network can overcome the issue of reduced horizontal components of the vector in the electric signal obtained from the patch-type device attached to the anterior chest. The reconstructed 12-lead ECG that uses the LSTM network was tested against a standard 12-lead ECG in 30 healthy subjects and ECGs of 30 patients with pathologic findings. The average correlation coefficient of the LSTM network was found to be 0.95. The ability of the reconstructed ECG to detect pathologic abnormalities was identical to that of the standard ECG. In conclusion, the reconstruction of a standard 12-lead ECG using a three-lead patch-type device is feasible, and such an ECG is an equivalent alternative to a standard 12-lead ECG.
Sohn et al. (Tue,) conducted a observational in Healthy and pathologic ECG findings (n=60). Reconstructed 12-lead ECG using a three-lead patch-type device and LSTM network vs. Standard 12-lead ECG was evaluated on Correlation coefficient between reconstructed and standard 12-lead ECG (Correlation coefficient 0.95). Reconstructing a 12-lead ECG from a three-lead patch-type device using an LSTM network achieved an average correlation coefficient of 0.95 compared to a standard 12-lead ECG.
