** In ''Part 4'', the Third Bomb of Yoshikage Kira's Killer Queen [[FightingSpirit Stand]], aptly named Bites the Dust, runs off this trope. Once somebody tries to find out Kira's identity through the person that Bites the Dust is implanted on, in this case being [[KidHero Hayato Kawajiri]], Bites the Dust appears and enters the pupil of whoever just asked Hayato for the information, with no way to be counterattacked. From there, it sets off the bomb, causing the person to [[DefeatEqualsExplosion explode from the inside out]]. Also, because Bites the Dust runs off of a GroundhogDayLoop, rewinding time by one hour after a new person dies, it {{exaggerate|dTrope}}s this trope by causing anybody who died in the previous loop to explode again without even needing to be activated, and the loop won't restart following their death.

* Shallow water blackout. Don't hyperventilate before breath-hold diving. Hyperventilating increases the rate where the body takes in oxygen, and having it stop immediately/abruptly by breath-holding can cause the person to pass-out. After this, the body reacts and tries to breath, which when underwater, can cause drowning.

* Any form of Aortic Rupture is frequently this. The Aorta is the largest artery in the body, where nearly all blood flows through from the heart. As such, rupturing this artery, whether through injury or trauma (e.g. stab or bullet wound), is highly fatal and will cause death within minutes. And because the blood pressure the aorta naturally has is high, it's nigh-impossible to stop the bleeding, much less if it's internal. Victims rarely survive this injury, even if they make it to the hospital alive, with a fatality rate of 90%. Relatedly, there is a serious and potentially fatal condition known as an aortic dissection, which started garnering attention in 2003 when one claimed the life of actor Creator/JohnRitter and, a little less than two decades later, from the death of mangaka Creator/KentaroMiura in 2021. The symptoms can be confused with other more common events like a heart attack or stroke, meaning the correct diagnosis may come too late.

-->An aortic dissection is a serious condition in which the inner layer of the aorta, the large blood vessel branching off the heart, tears. Blood surges through the tear, causing the inner and middle layers of the aorta to separate.

* Secondary drowning, which is pulmonary edema (the lungs getting filled with liquid) sometime after the inhalation of fluid.

* Shallow water blackout. Don't hyperventilate before breath-hold diving.

* In ''VideoGame/NewHorizons'', Captains could find themself fighting a whole group of people alone, without being able to run away or force them into chokepoints : might as well save themself some time and reload.

** To attack a town or board a ship, then seeing that crewmen are getting slaughtered like pigs, and an angry mob of defenders is now running towards : a simple reload of the last save should take players away from the trap.

* A tactic of some predators for taking down large prey is to pounce on their victim, severely wound a vital region, and then let the prey escape. The prey animal manages to run away from the predator but succumbs to its injuries much later, and the predator simply follows the scent trail left by the wounded victim in order to find its dinner.
** Most often done by some venomous snakes, who bite a small animal, such as a rodent, then releases the victim (which is a wise choice for the snake, as struggling prey can try to fight back and injure it). As the venom takes a while to take effect, the animal is still able to run for a good distance before collapsing: fortunately for the snake, its well-developed sense of smell helps it track down the downed prey.
** This includes humans (prior to the advent of firearms), as they would inflict injuries - sometimes grievous ones - on prey and then utilize our status as a SuperPersistentPredator to keep pushing the prey to the point of exhaustion or outright death.

* Rabies. By the time one starts showing any symptoms at all, the virus has already made it to the brain, at which point there is next to no chance of survival. Only a handful of people have ever reached that stage and lived to speak of it, and only after receiving an experimental treatment called the Milwaukee Protocol, which involves an induced coma. Even then the survival rate was only 4 out of a little over 30 attempted cases, 3 of whom came out with permanent brain damage.[[note]]The one saving grace is that rabies takes days to weeks to progress to that stage and there ''is'' an effective treatment protocol for pre-symptomatic rabies, so if a person ''knows'' they've potentially been exposed, they can get treatment right away and will almost certainly survive if they do. However, if a person doesn't realize they've been exposed or fails to recognize the danger, by the time they realize their mistake it will likely be too late.[[/note]]

* Something resembling a "five-point palm exploding heart technique" is theoretically possible. A [[OneHitKill strong blow]] to the area of the chest in front of the heart (precordium) during the small period in which the heart is highly sensitive to mechanical or electrical disruption can induce ventricular fibrillation, which produces light-headedness followed quickly by unconsciousness and shortly thereafter death unless immediate medical attention is provided. This is called [[https://en.wikipedia.org/wiki/Commotio_cordis Commotio cordis]] and does happen on occasion to young athletes, especially children, such as when they are struck in the chest by baseballs; this is also the condition that caused American football player Damar Hamlin to suffer a cardiac arrest mid-game[[note]]in fact, that incident gives a pretty clear picture of how the condition progresses; Hamlin initially stood up after making the tackle, seemingly unharmed, before stumbling and collapsing to the ground; thankfully, Hamlin's case did ''not'' end in death, but it very easily could have if not for the competence and immediate reaction of the on-site medical staff[[/note]]. An elevated heart rate provides more opportunities for a fatal disruption to occur. However, the window of vulnerability is so fleeting (on the order of a few tens of milliseconds) that doing this ''intentionally'' to a person without them being hooked up to a heart monitor (and knowing precisely when during the cardiac cycle to time the blow) would be functionally impossible unless they just happened to hit it perfectly by sheer dumb luck (which is why every documented case in history has been accidental).
