• #1 Sudden cardiac arrest: Symptoms, treatment and prevention – UAB News

  https://www.uab.edu/news/health-medicine/sudden-cardiac-arrest-symptoms-treatment-and-prevention

  Sudden cardiac arrest occurs when the heart suddenly stops beating. Unlike a heart attack, which occurs from a blockage that limits blood flow to a part of the heart, SCA occurs when the heart loses function due to an irregular heart rhythm, causing breathing to stop and the individual to become unconscious. SCA can occur in anyone at any age. […] The typical signs of a cardiac arrest include abrupt loss of consciousness with eyes rolled back, seizure-like activity due to lack of oxygen flow to the brain, and irregular, labored or no breathing, said Irfan Asif, M.D., professor and chair of the UAB Department of Family and Community Medicine. Additionally, someone suffering from SCA may have a very weak pulse or no palpable pulse at all. […] Other symptoms that may precede SCA include chest discomfort, shortness of breath, weakness, and heart palpitations such as a fast-beating, fluttering or pounding heart. However, SCA will occur without any warning, which is why experts say it is important to know how to respond when someone is experiencing SCA.

• #2 Sudden Cardiac Arrest: Causes & Symptoms

  https://my.clevelandclinic.org/health/diseases/21736-cardiac-arrest

  Cardiac arrest happens when your heart stops beating or beats so fast that it stops pumping blood. During cardiac arrest, people typically collapse and become unresponsive. Symptoms start without warning. This is why people also call it sudden cardiac arrest. […] Sudden cardiac arrest happens without preceding symptoms. […] Cardiac arrest symptoms may include: Loss of consciousness (fainting), Heart palpitations, Dizziness, Lightheadedness, Weakness. […] Before cardiac arrest, abnormal, rapid impulses abruptly override the normal electrical impulses that start your heartbeat. […] Abnormal heart rhythms (arrhythmias) cause most sudden cardiac arrests. The most common life-threatening arrhythmia is ventricular fibrillation (also called v-fib). This is an erratic, disorganized firing of impulses from your heart’s ventricles (lower chambers). When this happens, your heart can’t pump blood. […] Without treatment, you can die within minutes. […] Sudden cardiac arrest can be fatal if it lasts longer than eight minutes without CPR. Brain damage can happen after just five minutes. […] Survival without brain damage is far more likely with early CPR and defibrillation.

• #3 Sudden Cardiac Arrest vs. Heart Attack: Know the Signs, Save a Life

  https://www.uchealth.com/en/media-room/articles/know-the-signs-help-save-a-life-sudden-cardiac-arrest-vs-heart-attack

  In cardiac arrest, the event will be sudden—the person’s heart will stop and you will not be able to detect a pulse. They will also become faint, unconscious, and stop breathing. […] Sudden cardiac arrest occurs when there is an electrical problem within the heart, rather than an obstruction in its supply lines. With this electrical malfunction, the heart stops pumping oxygen-rich blood through the body, which puts organs at risk of damage—including the heart itself. This results in loss of consciousness and can be fatal, or result in brain damage, if not treated immediately with CPR. […] Three signs of cardiac arrest that are not signs of a heart attack include sudden loss of consciousness, lack of pulse, and no breathing. Other symptoms, such as dizziness or chest pain, may also indicate cardiac arrest, but they may also be associated with other conditions, like a heart attack. Therefore, it is important to observe the entire range of symptoms before making any conclusions. […] When a person suffers from cardiac arrest, survival depends on immediately receiving CPR.

• #4 Sudden cardiac arrest: 5 things women need to know | UCLA Health

  https://www.uclahealth.org/news/article/sudden-cardiac-arrest-5-things-women-need-to-know

  Most people think of the heart as a pump. But the fundamental property that makes it work the way it does is electricity, Dr. Ajijola says. If that electrical system is damaged or injured, it can alter how electricity spreads through the heart and cause chaotic electrical activity. If not immediately corrected, sudden cardiac arrest quickly leads to death. […] If you have heart disease or previously had a heart attack, your risk for SCA greatly increases. Many people have a heart attack and do not have sudden death, Dr. Ajijola says. But if youve had a heart attack, the heart is clearly not working well and your risk for SCA goes up. […] Cardiac arrest may be caused by most heart conditions, but other factors do play a role. Risk factors for SCA in women include: […] Cardiac arrest is not as common in women as in men. But all the same heart-related factors that cause SCA in men also cause it in women. The problem for women, according to Dr. Ajijola, is that the signs of heart disease are not always as obvious.

  https://www.mayoclinic.org/diseases-conditions/sudden-cardiac-arrest/in-depth/sudden-death/art-20047571

  Sudden cardiac death is the swift and not expected ending of all heart activity. Breathing and blood flow stop right away. Within seconds, the person is not conscious and dies. […] Sudden cardiac death is different from sudden cardiac arrest (SCA). SCA is the sudden loss of heart activity due to an irregular heart rhythm. Survival is possible with fast, proper medical care. […] Most sudden cardiac deaths are in older adults, particularly those with heart disease. Yet sudden cardiac arrest is the leading cause of death in young athletes. […] Changes in the heart’s electrical signaling often causes sudden cardiac death. A very fast heartbeat causes the lower heart chambers to squeeze fast and in a way that is not coordinated. The heart can’t pump blood to the body. This life-threatening type of irregular heartbeat is called ventricular fibrillation.

  Sudden cardiac death (SCD) is a sudden, unexpected death caused by a change in heart rhythm (sudden cardiac arrest). […] Some people may experience symptoms of sudden cardiac arrest, such as a racing heartbeat or feeling dizzy, alerting them that a potentially dangerous heart rhythm problem has started. In over half of the cases, however, sudden cardiac arrest occurs without prior symptoms. […] Most sudden cardiac deaths are caused by abnormal heart rhythms called arrhythmias. The most common life-threatening arrhythmia is ventricular fibrillation, which is an erratic, disorganized firing of impulses from the ventricles (the heart’s lower chambers). When this occurs, the heart is unable to pump blood and death will occur within minutes, if left untreated. […] Yes, sudden cardiac arrest can be treated and reversed, but emergency action must take place immediately. Survival can be as high as 90% if treatment is initiated within the first minutes after sudden cardiac arrest. The rate decreases by about 10% each minute longer it takes to initiate therapy. Those who survive have a better long-term outlook.

[…] Every second counts in cardiac arrest. Recognizing cardiac arrest and activating the EMS system, immediately beginning CPR, and using an AED as soon as possible gives the person the best chance for surviving the incident. […] Chest compressions pump a small amount of blood around the body to keep the organsmost importantly the brainalive. You may not see any visible change in the person’s condition, but don’t give up. Chest compressions significantly increase the possibility of the person being successfully resuscitated when EMS arrives and continues care. The chance of restarting the heart by chest compressions alone is very low. To restart, a heart usually needs an electric shock from a defibrillator.

  Urgent CPR is critical. By maintaining a flow of oxygen-rich blood to the body’s vital organs, CPR can provide a vital link until more-advanced emergency care is available. […] A portable device which momentarily stops the heart and the chaotic rhythm, often allowing the normal heart rhythm to resume. The procedure delivers a therapeutic dose of electric currents to the heart. If a defibrillator is available, it should be used as soon as possible.

  Sudden cardiac arrest (SCA) is the medical term for the sudden loss of heart function. Its different from a heart attack and often occurs without warning. However, experts now say that sudden cardiac arrest may not be so sudden or subtle after all. In a study published in The Lancet, investigators found that half of all people who have sudden cardiac arrest will feel symptoms the day before. Whats more, the study also suggests that the signs are different in men than in womenwith men feeling chest pain and women experiencing shortness of breath. […] Sudden cardiac arrest happens when the heart suddenly stops beating, and no blood is pumped to the brain and other vital organs. If left untreated, the chances of survival may be slim. Someone is likely having a cardiac arrest if they: Collapse or pass out suddenly, Are not breathing, or are gasping for air, Do not respond to shaking or shouting, Have no pulse. […] Shortness of breath and chest pain can be telltale signs, but these symptoms can occur for other reasons. If you see that someone is unconscious or gasping for air, they may be in cardiac arrest.

  In more than half of the cases of SCA in children, death was completely unexpected. Young people are often unaware of the risk factors and dont tell adults when they experience the symptoms. They may be frightened, embarrassed or simply unaware that what they are feeling indicates a potentially fatal problem. […] Educating parents, children and teenagers about the symptoms and risk factors of SCA is one way to help prevent it.

  Given that SCA is not a common occurrence but can have devastating outcomes, it is important for people to be ready to act if something were to happen specifically in environments with increased risk, including sporting events or practices, said Cam Hebson, M.D., associate professor in the UAB Department of Pediatrics. […] When SCA occurs, many people never respond, because they do not know how to respond. When someone is experiencing SCA, every minute that person does not receive CPR decreases their chance of survival by 10 percent, according to the American Heart Association. That is why it is so important for people to know how to use these tools for survival.
