Where does come from?
The beating heart emoji, as its officially named, was approved under Unicode 6.0 in 2010.
Depending on the platform, the beating heart emoji is pink or red, a color shared by many of the other (over two dozen) heart-themed emoji. It is distinguished, however, by the short, curved motion lines above its two chambers, representing a pulsing heartbeat.
Twitter's beating heart emoji design, notably, features motion lines that are yellow, with most other vendors match the line and heart colors.
Over the 2010s, the emoji's illustration of a heartbeat has lent it more energy and intensity in its expression of love and excitement than its static heart counterparts. Since it portrays a pulse, the beating heart emoji has given itself to contexts of health and wellness, the presence of a heartbeat indicating life and vitality.
Who uses ?
Along with other heart-themed emoji, the beating heart emoji is very popular on social media and in text and instant messages to communicate and emphasize a heightened sense of affection.
Its symbolic pulsing is often used to mark an exuberant joy and obsessive-seeming adoration, especially when fans are fawning over a popular singer or actor they love. The emoji is frequently used in a string and paired with other heart emoji for additional effect (e.g., OMG this picture of Justin Bieber 💓💓❤️💕💕💛). In this context, the beating heart emoji can be roughly synonymous with a heartthrob.
The beating heart emoji also often tags expressions of personal love and friendship, "I love you 💓" or "Can't get enough of my bestie! 💓".
Health bloggers and healthcare providers, especially those focused on cardiovascular health, also incorporate the beating heart emoji into their online messaging. The implication of the emoji in this context is that a beating heart is a healthy heart, essential to overall wellness.
In online content, it is not uncommon to see the beating heart emoji in titles or descriptions of heart health information, workout plans, and materials about self-improvement, meditation, and yoga. People may also use the beating heart emoji after a particularly revitalizing workout or act of self-care (e.g., I felt so great after my pilates class 💓).
