Nowadays, Electrocardiogram (ECG) signals can be measured using wearable devices, such as smart watches. Most wearable devices provide only a few details; however, they have the advantage of recording data in real time. In this study, 12-lead ECG signals were generated from lead I and their feasibility was tested to obtain more details.

Abrupt changes in the hemodynamics after surgical correction of valvular heart disease (VHD) can lead to alterations in ventricular repolarization. We compared the difference between temporal changes in repolarization parameters after correction of left-sided VHD.

Article Synopsis
- The study focuses on improving ECG measurement methods by using a generative adversarial network (GAN) to synthesize multiple ECG signals from a single-lead ECG.
- Traditional ECG methods, which measure heart activity through multiple electrodes, often lack detailed information when using single-lead devices.
- Results show that the low Fréchet distance and mean squared error scores indicate a strong similarity between the synthesized and reference ECG, making the method suitable for wearable devices.
