Death is defined as when the heart has stopped and cannot start again. It is possible for people to be “brain-dead” or in a coma, etc. while their heart continues to beat and thus technically they are still alive, but when the heart has come to a complete halt, then life has ended.
Yes but I guess what I am asking is, can a lack of oxygen stop the heart? I suppose the easy answer is “yes it is possible” but how common is that? Usually (my impression only) it’s the other way around. Lack of oxygen is caused by bad pulmonary system, drowning, sitting in a running car in a closed garage, or a heart attack. Can lack of oxygen cause cardiac arrest? My impression is that the heart will continue to pump, it just won’t be pumping oxygen and then the other organs will fail. Then the heart will stop. But as always I am open to correction and education.
No. Brain death can be declared while the heart is still beating
Liberals defending Planned Butcherhood will tell you that life does not begin when the heart starts beating. If they're correct, life cannot end when the heart stops. Their logic ties them in knots.
