are you dead when your heart stops?

Sudden Cardiac Arrest. Sudden cardiac arrest occurs when the heart suddenly stops beating, which stops oxygen-rich blood from reaching the brain and other organs. A person can die from SCA in minutes if it is not treated right away.

Well, hang on. While the stress of grief may bring on general health impacts, there is a legitimate and specific medical condition called "taktsubo cardiomyopathy" — or heartbreak syndrome — that doctors say is dying of a broken heart. But it's incredibly rare.

Death is pronounced after cardiac activity stops. Death usually occurs within seven minutes, although, due to complications in finding a suitable vein, the whole procedure can take up to two hours, as was the case with the execution of Christopher Newton on May 24, 2007.

In short the answer is no; there is a misconception that the heart stops during an SCA. In fact it continues to beat in an irregular way (fibrillation) which prevents it from pumping oxygenated blood around the body to the brain and other vital organs.

Once someone stops breathing, his body can no longer get oxygen and the heart muscle will die and stop beating, even with a pacemaker. Therefore, the pacemaker will not prevent death and a patient will die from his terminal illness without turning off the pacemaker.

In addition, when a person is closer to death, the hands, arms, feet, or legs may be cool to the touch. Some parts of the body may become darker or blue-colored. Breathing and heart rates may slow. In fact, there may be times when the person's breathing becomes abnormal, known as Cheyne-Stokes breathing.

Organ and Tissue Donation after Cardiac Death Typically when a person suffers a cardiac death, the heart stops beating. The vital organs quickly become unusable for transplantation. But their tissues – such as bone, skin, heart valves and corneas – can be donated within the first 24 hours of death.

In fact, when your heart doesn't beat normally, its electrical system is likely out of step. When your heart beats too fast, too slow, or skips irregularly, it is called arrhythmia. Your heart can't pump blood through your body well, and that can cause damage to your lungs, brain, and other organs.

Prevent Brain Death CPR effectively keeps blood flowing and provides oxygen to the brain and other vital organs, giving the victim a better chance for full recovery. Everyday Health reports that If CPR is given within the first two minutes of cardiac arrest, the chances of survival double.

Difference between heart attack and cardiac arrest. You are conscious during a heart attack, but you are unconscious, not breathing, and technically dead during cardiac arrest.

Congestive heart failure doesn't mean your heart has stopped. It means it's not pumping blood the way it should. When that happens, blood and fluid can back up in your body and make it harder for your kidneys to flush out sodium and water. That can make you hold on to too much fluid, which causes swelling.

Even though panic attacks can feel like a heart attack or other serious condition, it will not cause you to die. However, panic attacks are serious and need to be treated. If you find yourself experiencing any of these symptoms on a regular basis, it's essential that you contact your physician for further help.

Loved ones might find it hard to comprehend that someone is dead when he still feels warm to the touch and his chest continues to rise and fall as a result of mechanical support, Tawil says. “What they hear is 'kind of dead,' 'maybe dead,' 'sort of dead,' but they don't hear 'dead,'” Caplan says.

If your heart rate drops into the 30s, you might not get enough oxygen to your brain, making fainting, lightheadedness, and shortness of breath possible. Blood can also pool in your heart chambers, causing congestive heart failure.

Once the dead twin's heart stops, blood stops pumping, the vessels dilate, and the conjoined twin will essentially bleed into the dead twin. If that doesn't happen acutely — say it's a small connection — there will be an infection in a matter of hours.

Defibrillation reverses the cardiac arrest by sending an electrical current through the heart muscle cells, momentarily stopping the abnormal electrical energy and allowing the normal heart beat to resume. ... Greater than 50-70% of Sudden Cardiac Arrest victims survive if defibrillation occurs within the first 5 minutes.

If someone without a pulse appears to recover and regain a pulse through CPR then the chances are that their heart was still beating faintly all along. So don't be surprised if someone doesn't immediately come back to life.
