The image displays a simple, black and white line drawing of an ECG (electrocardiogram) heartbeat pattern. The pattern consists of a series of peaks and valleys, representing the electrical activity of the heart. The peaks are labeled with the letter "R," which stands for the R-wave, a part of the ECG signal that indicates the start of the cardiac cycle. The valleys between the peaks are the T-waves, which represent the repolarization of the heart. The image is a graphic representation, likely used for educational or informational purposes to illustrate the concept of an ECG heartbeat pattern.
