"What if my heart beats faster?" is a song by Jorja Smith. If you are asking about the physical implications of your heart beating faster, it could be due to a variety of reasons, such as exercise, stress, or excitement. When your heart beats faster, it is pumping more blood to your body to meet the increased demand for oxygen and nutrients. This can be a normal response to certain situations, but if you experience an irregular or rapid heartbeat frequently, it is important to consult a doctor to rule out any underlying medical conditions.
