The image displays a series of black and white line graphs, each representing a different ECG (electrocardiogram) reading. These graphs are arranged in a horizontal line, creating a pattern that resembles a wave or a series of waves. Each graph consists of a series of peaks and troughs, typical of an ECG reading, which is used to measure the electrical activity of the heart. The style of the image is simple and graphic, with a clear focus on the ECG patterns.
