That is very misleading statement.
How long did the heart stop, starving the brain of the oxygenated blood is the criteria. As I have pointed out heart stoppes in so many cases, but the person is not dead. If stopping of heart was death, then there will be no need for pacemakers.
Some people's heart beat stops for several seconds, and they don't die. It is possible that the electrical system of the heart can not function properly and cause prolonged pauses in the conduction system of the heart. This is called Sick Sinus Syndrome. The person may feel very weak, fatigued, some may black out. They don't stop breathing. These people usually end up with a pacemaker!
People have been revived from things like cold water drowning after as much as an hour. You actually die when the brain is starved for oxygen long enough for it to begin the death process.
Look up "Clinical Death" and "Biological Death".
Just as in the case of brain death, stopping of heart beat should irreversible. That's when the heart totally fails. But even with irreversible brain death given our current knowledge, there would be signs of life.
The point is that it invariably needs a heart to show signs of life.
