Hearts are the standard HP for most characters and can be found in various varieties. The player cannot have more Red Hearts than Red Heart containers, but certain heart pickups can circumvent that limit.

Heart	ID	Image	Worth	Additional Info	Unlock Method
Red Heart	5.10.1			Heals with Maggy's Bow. Humbling Bundle and Equality! can replace this with a Double Heart.
Half Red Heart	5.10.2			Heals with Maggy's Bow.
Double Heart	5.10.5			Doesn't spawn naturally. Can only be found by using certain items or encountering certain rooms. Has a 1/20 spawn rate in Normal Mode and 1/50 in Hard Mode. Heals with Maggy's Bow.
Scared Heart	5.10.9			Identical to the standard Red Heart but pulses faster. It will run away as the player moves towards it. Heals with Maggy's Bow. Humbling Bundle and Equality! will not double this.	Reset 7 times in a row Switch PS4 Get a minus 10-win streak
Soul Heart	5.10.3			Soul Hearts are blue hearts that are added to the end of the health bar. Soul Hearts are not permanent; once lost, they cannot be replenished, although new ones may be added. Soul Hearts will be depleted before Red Hearts in most cases. However, donating to a Blood Donation Machine or a Devil Beggar will deplete Red Hearts first as long as you have more than half a Red Heart (a full heart in Womb and beyond). Holding the Crow Heart trinket will also deplete Red Hearts before Soul Hearts.
Half Soul Heart	5.10.8			Replaces regular soul heart drops. Like whole soul hearts, they can be used to refill a half black heart.	Reset 7 times in a row Switch PS4 Get a minus 10-win streak Defeat Mom's Heart 5 times
Blended Heart	5.10.10		//	Fills up a full Red Heart container, but will act as a Soul Heart when no containers are free. If Isaac is only missing half a Red Heart, it will fill that half, and give him half a Soul Heart as well. Dark Bum and The Jar will not collect this. Heals or with Maggy's Bow.
Black Heart	5.10.6			When fully lost, it will damage all enemies in the room for 40 damage, similar to The Necronomicon's effect. Acts like a Soul Heart otherwise.
Eternal Heart	5.10.4			When held until the next floor, Eternal Hearts will grant Isaac a Red Heart container. They will also give a Red Heart container if two are collected on the same floor. Eternal Hearts are placed in the second half of the last Red Heart container or Bone Heart, even when it is full (the Eternal Heart will overlap with the Red Heart in this case).
Gold Heart	5.10.7			Gold Hearts do not actually add more health, instead forming an outline around the last heart in Isaac's health bar. When that heart is depleted, the Gold Heart will break and a few coins will be dropped around Isaac. Gold Hearts flash when depleted and will temporarily turn enemies golden like Midas' Touch.	Complete XXXXXXXXL (challenge #21)
Bone Heart	5.10.11			Takes three hits to deplete and can be refilled with Red Hearts, but disappears permanently upon depleting. Cannot be refilled as ???, Tainted ??? Dark Judas, Tainted Judas, Tainted Forgotten or Tainted Bethany and only protects against one hit as these characters.	It's complicated
Rotten Heart	5.10.12			Rotten Hearts fill up one whole heart container, or the rightmost Red Heart if all of Isaac's heart containers are full. (It isn't possible to have one-half a Rotten Heart; they are always depleted in one hit.) Each Rotten Heart in Isaac's life bar spawns two Blue Flies upon clearing a room.	Enter the Corpse for the first time

Notes

More details on these pickups and how they work can be found here.

• Eternal Hearts take half a heart of damage without counting as a hit for the Devil/Angel Room to spawn.
• Unless an item effect specifically states it, a Red Heart always has the chance to be replaced by a Soul, Black, or Eternal Heart.
• Red Heart pickups created by item, card, or pill effects can be forced to be spawned as Black or Eternal Hearts instead by using the item, card, or pill in a relevant Super Secret Room.
• If Isaac's health bar is filled with Soul Hearts, picking up a Black Heart will replace the topmost Soul Heart.
  • If Isaac's health bar is filled up to 11 1/2 (Soul/Black) Hearts with the last one being half a Black Heart, picking up a Black Heart will fill that one and convert a full Soul Heart to a Black Heart (therefore adding half a Black Heart and converting a Soul Heart).
  • If Isaac's topmost heart is a Half Soul Heart, collecting a Black Heart will complete it into a whole Soul Heart, and add half a Black Heart.
  • Collecting a Soul Heart with half a Black Heart left will complete the Black Heart, and add half a Soul Heart. The reverse is also true.
• Rotten Hearts can fill Bone Hearts.
• Rotten Hearts are only donated to the Blood Donation Machine after all Red Hearts are depleted.
• If Rotten Hearts have not been unlocked yet, any room layouts containing them (including the Corpse Super Secret Room) will instead contain Half Red Hearts.
• Losing Rotten Hearts does not lower the chance of the Angel Room or Devil Room appearing.

Trivia

• There are unused graphics for Half Soul Hearts and Half Black Hearts that are never seen ingame.
  • Half Soul Hearts were eventually added to the game as an unlockable.
• Booster Pack #5 made Scared Hearts beat faster, making them slightly easier to spot. This was from this Steam Workshop mod by piber20.
• Gold Hearts' appearance was changed in Booster Pack #5.
• Most items that grant Black Hearts upon being picked up say "evil up" in their description.

Bugs

Bug!

Gold Hearts actually simply compare Isaac's current heart count to what he had on previous frame, leading to two bugs. Firstly, it's possible for a Gold Heart to burst when health other than the rightmost heart is lost, such as using up Red Hearts with a Blood Donation Machine. Secondly, the "previous frame hearts" value is updated incorrectly; a Gold Heart bursts immediately upon pickup if Isaac had and lost a Gold Heart earlier, and his current heart count is lower than after losing the previous one.

Bug!	With 2 or more Rotten Hearts and an Eternal Heart, if Isaac takes a full heart damage, the second Rotten Heart will turn into half a Red Heart.
