From: A deep learning approach identifies new ECG features in congenital long QT syndrome
QRS complex comparison. The median QRS complex of 100 control ECGs (black lines) was retrieved and compared to the median QRS complex of the corresponding LQTS1/2/3 ECGs (green lines) analyzed by the best performing DL models (left). The median QRS complex from the control ECGs and LQTS ECGs was then calculated (right). On the x-axis data points from the waveform are shown; 25 data points correspond to 0.10 s or 100 ms
