What happens to the heart after drowning?

In fresh water drownings inhaled water is immediately absorbed into the blood causing hemodilution. The diluted blood quickly leads to heart failure due to ventricular fibrillation, a condition simply described as shivering of the heart, or anoxia (oxygen starvation).

What happens to the heart when drowning?

Drowning may result in an acute asphyxial cardiac arrest, which emanates from hypoxemia that precedes the development of ischemia. This scenario results from initial cessation of gas exchange followed by worsening hypoxia and eventual cardiac arrest. Hypoxemia is the overriding insult.

Why does the heart stop after drowning?

A lack of oxygen or chemical changes in the lungs may cause the heart to stop beating. This cardiac arrest stops the flow of blood and thus stops the transport of oxygen to the brain.

How long does it take for the heart to stop after drowning?

“Finally, the heart will slow down because it hasn't got any oxygen. Usually, they've been unconscious for three to five minutes in the water.” It takes an average of two minutes for someone drowning to become unconscious. That's about the same time as it takes to brush your teeth (properly).
