Conventional heart symbol
A heart symbol pierced with an arrow, symbolizing romantic love (being lovestruck, or the pain of lovesickness)
A typical depiction of the Sacred Heart (often shown with other attributes, e.g. surmounted by a cross, pierced by nails or swords, etc.)
The heart symbol is an ideograph used to express the idea of the "heart" in its metaphorical or symbolic sense. Represented by an anatomically inaccurate shape, the heart symbol is often used to represent the center of emotion, including affection and love, especially romantic love. It is sometimes accompanied or superseded by the "wounded heart" symbol, depicted as a heart symbol pierced with an arrow or as a heart symbol "broken" into two or more pieces, indicating lovesickness.
