The image displays a simple, black and white line drawing of an electrocardiogram (ECG) heartbeat graph. The graph consists of a series of horizontal lines that represent the electrical activity of the heart, with the peaks and valleys indicating the different phases of the heart's contraction and relaxation. The lines are evenly spaced and rise and fall in a smooth, rhythmic pattern, typical of an ECG reading. The image is clear and straightforward, focusing solely on the representation of the heartbeat without any additional context or embellishments.
