Apparently, the heart (being the organ responsible for powering the circulation of blood around the body) is an extremely romantic thing. Hence, "hearts" are equated with positive emotions, such as love, kindness, and compassion. According to this logic, someone that lacks ability to sufficiently feel such emotions is "heartless," and someone that has recently experienced a romantic tragedy is "heart-broken."
When a Heart Symbol is used for this, it's traditionally pronounced "love," as in "I love New York" for "I ♥ NY," although recent convention has been to actually pronounce the symbol as "heart" — for example, the film I Heart Huckabees. This in turn has led to the Internet meme of typing "I less-than-three X," in reference to the mathematical meaning of "<3".
In Animation and Graphic Novels, a cloud of hearts drawn floating near a character's head sometimes indicates a character falling in love and/or lust. Eyes popping out in the shape of hearts, oversized heartbeats, and the like are all some of The Oldest Ones in the Book.
The reason for this goes back to ancient days when people could do little more than guess at why people had so many different weird bits inside them, let alone which ones did what. Different cultures decided on different organs as being the seat of emotions and/or intelligence; Some went with the intestines (such as the Hebrews of the Old Testament), some went with the kidneys, some went with the Heart, etc. The Ancient Greeks were among the ones who went with the heart, and such was the strength of their influence on western civilization that many of our idioms and figures of speech still reflect the notion of the Heart being the cognitive organ, even though we've known it to be untrue for centuries.

- Older translations of The Bible use not only the heart, but the kidneys as a metaphor for centers of human thought and emotion. If you're not used to it, it can feel mildly sacrilegious to read passages where the original word for "affection" (NIV) is "bowels" (KJV).

They'll beat so much strongerThan they could apart
Eight chambers of muscle to hustle
The love in our heart

When he notices this, he immediately says "Excuse me, this is a serious heart condition, I gotta go!" Also counts as something of a PG-rated Something Else Also Rises.
- A Valentine's Day episode of The Simpsons also Deconstructed this by having the school cafeteria serve beef hearts for lunch on Valentine's Day. Needless to say, this did not make things more romantic.

- The ancient Egyptians took this trope one step further: they believed the heart was not only the center of the soul, and thus the "seat of emotions and will", but also the center of the nervous system.
- The heart has long been thought of as the seat of the emotions, while the brain was regarded as little more than "head stuffing". This thinking goes back to the ancient Egyptians, who preserved the heart of the dead but threw out the brain. It wasn't until the 6th century BCE that the idea of the brain as seat of intelligence was even forwarded, and Aristotle believed that the brain served to cool the blood (humans being superior to animals because, since our blood-coolers were larger, we were less hot-bloodedly irrational). Head wounds bleed profusely, so that being a good way to kill people was no contradiction.
- The heart being the seat of the emotions is cultural. Some cultures use the kidneys, some the liver, and, yes, some use the bowels. The only reason we went with the heart is because the Ancient Greeks did. See also the Biblical examples in Literature above.
- The heart does influence the nervous system more than the brain in formative years, it can take as long as seven years for a truly rational (and calorie hogging) brain to develop while the heart takes much less time to get there. Testable proof that the brain was the main thought center caused many people to disregard the heart's influence on behavior for centuries, showing fields in science often regress a little before truly moving forward as we now know all emotions have measurable effects on the heart's electrical field. More than a blood pump that produces a lot of electricity, the heart is also a hormonal gland that produces its own neurotransmitters, dopamine, epinephrin, norepinephrin, the catechlomines.
- Since heart transplants became viable, some recipients have reported changes in their personalities, tastes and desires that seem to mirror the donor's lifestyle. Comparing reported changes to the lives and preferences of the heart donors reveals no correlation.
- Starting with the ancient Greeks, the liver was claimed to control human passion. Later, medieval Europeans developed the idea that "humor," — blood, phlegm, black bile, and yellow bile — controlled health and temperament, and that a lack of yellow bile (anger, courage, spirit) would make the liver pale as a side effect. This is the origin of the insult "Lily Livered" since a pale or white liver was a weak one thus without emotion or courage. Humors are the justification behind blood-letting, as well.
- The heart being responsible for delivery of oxygen to the body's active tissues, disorders that impair its efficiency can have an indirect, but genuine effect on a person's moods, making them feel more tired and sluggish. Not a state of mind normally associated with intense romantic desire.
- A possible explanation for this may be the increase in heartbeat when in the presence of someone you have a crush on, or maybe the fact that, for a good part of history, the heart was known as the "main life organ". ❤
- The idea that the heart is the seat of emotions is often attributed to the Greek philosopher Empedocles, though he may not have been the first to suggest it.
- Note that not all cultures equated love with the heart. The people of Elizabethan England, for instance, believed that the passions were seated in the liver, and the residents of Ancient Israel thought the bowels held such emotions (hence the term, a "gut feeling").

- It remains to clear up why the heart ♥ does not look especially heart-shaped. As always, watchers of the German Mouse know it all. <tl;dr> version: The "heart" is a leaf. Long version.
- The company Locum attempted to incorporate the heart symbol into their logo, replacing the O in their name with the heart, and it caused a few laughs because it made their company name sound like they love...something else.
- Anthropologist Desmond Morris, in his book Manwatching, speculated that the mystery of the heart symbol looking nothing like an actual heart, and its association with romance, has to do with a part of the body a long way away from the heart. He demonstrated that the human buttocks mimic the heart symbol, and pointed out that humans are hardwired to look for a nicely formed bottom as an indicator that a potential mate is both desirable and healthy. This behavior, Morris pointed out, is also prevalent in higher primates such as apes and monkeys.
