The term "tibok-tibok" refers to the rhythmic sound produced by the heart, often described as a heartbeat. This sound is created by the closing of heart valves as blood flows through the heart chambers. It is an essential indicator of cardiovascular health and is typically measured using a stethoscope during medical examinations. In some cultures, "tibok-tibok" can also symbolize emotions, particularly love and excitement. The phrase is often used in songs and poetry to convey the feeling of a racing heart when someone is in love or experiencing strong emotions. This connection between the heartbeat and feelings makes it a popular theme in various forms of art and literature.
