ECG	Electrocardiogram
QRS complex	Combination of three of the graphical deflections (Q wave, R wave, and S wave) seen in a typical ECG record. It represents an electrical impulse spreading through the ventricles of the heart and indicating their depolarization
Conv1d	Layer in Deep Neural Networks that performs a convolution on a one-dimensional signal
MaxPool1d	Layer in Deep Neural Networks that performs a pooling operation by selecting the maximum value from the moving window
Fully-Connected	Layer in Deep Neural Networks that consists of neurons, each of which process the whole of the input data
Leaky ReLU	Activation function used in Deep Neural Networks
Padding	Parameter used in convolutional layers specifying the amount of zeroed samples added to the start and end of the processed signal. For example, a padding of 1 means that there is one sample of value zero artificially added at the beginning and at the end of the signal. This operation is conducted in order to mitigate activation map shrinkage due to application of convolution
Stride	Parameter used in convolutional layers specifying the shift distance between subsequent windows of convolutions. For example, a stride of 1 means that the next convolution starts right after the the beginning of the previous one, so the windows will overlap (provided that kernel size is bigger than 1)
