Cardiovascular Love
Now you know it's serious.

"I ♥ _____"

An exceedingly common love trope that stipulates the following:

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."

In Animation and Graphic Novels, a cloud of hearts 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. See Heart Symbol for more examples.

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.

Please 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").

  • Apparently, a heart that was two sizes too small was responsible for The Grinch's lack of fondness for Christmas. The trope is played straight in the most literal sense possible.
  • 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).
    • A Christian comedian Mark Lowry once commented on this, resulting in "Oh, baby, you MOOOVE me! You move my bowels!" He then proceeds to sing exerpts from several songs, replacing "heart" with "bowels."
    • This occurs in many actual old hymns as well, resulting in Have a Gay Old Time. A particularly glaring offender remarks of God, "To me, to all, Thy bowels move."
  • The main plot point in The Wizard's Hairy Heart, a short tale and Book Within a Book in the Harry Potter universe: A twisted wizard seeks to remove all emotion from himself in order to become stronger, and so uses dark magic to physically extract his heart and store it in a container. It works better than he ever intended.

  • Averted (or possibly subverted) on The Wire with the gangster "No-Heart" Anthony: he got his nickname not from a reputation for cruelty, but because he once tried to escape arrest by shooting himself in the chest.
  • Lampshaded on Red Dwarf with the song Tongue-Tied.
    When I saw you for the first time (first time)
    My knees began to quiver (quiver)
    And I got a funny feeling (feeling)
    In my kidneys and my liver (digestive system baby)
    My hands they started shaking (shaking)
    My heart began a-thumping (boom boom boom)
    My breakfast left my body (huey huey huey)
  • In the Pushing Daisies episode Corpsicle, a boy who was waiting on a heart transplant (because he initially had no heart) was rather mean. A played straight example.
  • In Buffy the Vampire Slayer, Angel talks about this at length at one point. Buffy embraces him, and they have this exchange:
    Buffy: That's beautiful...(she opens her eyes) Or, taken literally, incredibly gross.
    Angel: I was just thinking that.
  • In Power Rangers Ninja Storm, the Big Bad's TV show in one episode (whoever watches gets brainwashed) was a sitcom called "I Love Lothor," with a heart for the logo... as in the actual, not-very-romantic-looking organ.
  • In the Supernatural episode "Hunteri Heroici" a Reality Warper is causing Cartoon Physics to take hold in the real world. The first sign of this is a man who goes to meet his mistressnote  and finds his valentine-shaped heart beating so aggressively that it explodes out of his chest, killing him.
  • On "The Big Bang Theory," Sheldon says the commonly used heart shape is actually modeled on the buttocks, prompting Penny to remark quizzically that she spent junior high drawing butts on her notebooks.

  • For Madison Eagles' match with Daizee Haze at CHIKARA Chaos in the Sea of Lost Souls, she wore a belt that on the back read "I ♥ Me."

  • In "Follow Your Heart" from Urinetown, the entire song has to do about following your heart more or less metaphorically, but one of Bobby's verses walks the line between romance and squick.
    Bobby: Someday I'll meet someone
    Whose heart joines with mine
    Aortas and arteries all intertwined
    They'll beat so much stronger
    Than they could apart
    Eight chambers of muscle to hustle
    The love in our heart

  • Played with and lampshaded in Digger: the hyena tribe view the liver, not the heart, as the most important organ and the source of a person's feelings.
    Ed: If Mousie is ever starving, Mousie will know. Prey's liver is what hunter craves first. Kill prey, eat liver, get strong. Full of feelings. Life. Heart just muscle.
    Digger: But you'd die without your heart!
    Ed: Not be getting far without liver, either.

    Western Animation 
  • Played annoyingly straight in Captain Planet and the Planeteers, "heart" refers to warm and fuzzy feelings and is also a (rather lame or rather awesome) superpower.
  • 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.
    • Another parody is when Moe sees a beautiful woman, mutters "You're BEAUTIFUL," and his heart flies forward from his chest like a cartoon. He immediately says "Excuse me, this is a serious heart condition, I gotta go!"
  • A Valentine's Day card made by Jimmy to Cindy in The Adventures of Jimmy Neutron: Boy Genius included a holographic realistic heart.
  • Lampshaded in Spongebob Squarepants. When Spongebob gives Squidward a shirt with "I ♥ U" woven into it, Squids reads it as "I Heart You."
  • Used as a visual gag in The Critic. On an especially lonely Valentines Day, Jay notices a newspaper with the headline "New York to New York: I [Heart] You!" with a smaller blurb underneith reading "Mayor Has [Heart] Attack."

    Real Life 
  • Valentine's Day plays this trope straight. (Thankfully for the cynics, there are chocolatiers that sell anatomically-correct chocolate hearts (e.g. here).)
  • offers heart themed items of geeky romance, including a pair of T-shirts with a bar of Zelda-esque hearts that light up when their wearers are near, and an anatomically correct gummy heart. It also features items with the "less than three" (<3) netspeak variant.
  • 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. 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.
