Slow Heart Rate More Condition_symptoms How Does Packing A Heart With Ice Slow The Heart Rate?

How does packing a heart with ice slow the heart rate? - slow heart rate more condition_symptoms

I know that the package is reduced with a heart of ice during the surgery, the heart rate, because metabolic rate is reduced, but I'm looking for more information.

So why the Q10 for the heart than in other parts of the body?

I am studying biomedical sciences at the University therefore does not have the need to simplify things to worry about.

Thank you.
