The image is an ECG (Electrocardiogram) graph, which is a visual representation of an electrical activity in the heart. The graph is divided into four sections, each representing a different stage of the ECG.

The first section is labeled "V1", the second section is titled "V2", the third section is labelled "V3", and the fourth section is marked "V4". The ECG lines are black and are arranged in a horizontal line, with the V1 section on the left side of the graph and the V2 section in the middle. The V3 section is represented by a series of curved lines, while the V4 section is shown by a straight line. The lines intersect at various points on the graph, indicating that the ECGs are in the same position as the V5 section. 

Overall, the graph shows a steady increase in ECG activity over time, indicating a decrease in the number of people who have been diagnosed with a heart attack.
