There are a lot of different ways someone could interpret how this sounds, heartbeats and lies. You could say it is something about love and the feeling of your heartbeating and then traumatizing feeling when the lie comes out. How your heart goes from beating fast to practiacally melting because of a simple lie. But as highschoolers, many people know the feeling of crushing, loving, and breaking; the heartbeats and the lies. On another hand, you could interpret the words as a helpful tool. It could simply be taken as a person can tell when another is lying becuase of their heartbeat. When you start to lie, your heartbeat speeds up even just a little. Some people can tell when someone else is lying by sensing their emotions and reactions. By this, it is a lesson that very frequently, by your reaction, heartbeats, and the lie, people can tell. Whether you intrepret the title by the heartbreaking stories or by someone who can see through others, when you are talking about heartbeats and lies in the same sentance, it usually does not send a happy message to people who can relate with heartbreak or simply who can relate to lies.
