The video shows a close-up of a computer screen with a heartbeat monitor displayed. A person's finger is seen pointing at different parts of the screen, presumably to indicate different aspects of the heartbeat monitor. The monitor shows a green line graph that represents the heartbeat, with peaks and valleys indicating the rhythm of the heart. The background of the screen is blue, and there is a red line that appears to be a marker or reference line. The person's finger moves along the screen, pointing at different parts of the graph, possibly to explain or analyze the heartbeat.
