What is sudden cardiac arrest?
Frequently Asked Questions about the Playing With Heart Prog...In people of all ages, sudden cardiac arrest is an abrupt loss of the heart's ability to pump blood. In most cases, it is caused by a sudden arrhythmia, such as ventricular fibrillation, in which the heart's electrical impulses create a dangerous and chaotic heart rhythm. When this happens, the victim collapses and quickly loses consciousness as blood flow to the brain is stopped. Unless a normal heart rhythm is restored within minutes, the victim will die or will suffer brain damage.

Frequently Asked Questions about the Playing With Heart Prog...A wide spectrum of cardiovascular abnormalities may cause sudden cardiac arrest in young athletes. A minor defect may become deadly if the heart is challenged and the electrical order of the heart is disrupted. Heart defects that may lead to cardiac arrest can be genetic or acquired due to a serious virus. Cardiomyopathy is the hidden heart defect that most commonly leads to sudden cardiac arrest in young athletes.

Frequently Asked Questions - Stop Heart Attack - Defibrillat...There are rarely warning signs before sudden cardiac arrest. However, SCA victims lose their pulse, lose consciousness, and then stop breathing. - Medtronic
Related QuestionsWhat Happens in a Sudden Cardiac Arrest?
Frequently Asked Questions .:. e-CircleOfLifeVictims of SCA are unresponsive, lose consciousness, stop breathing, and have no pulse. Most often, the victim is suffering from a heart rhythm disorder called ventricular fibrillation (VF). In this case, the victim needs CPR and defibrillation-an electric shock to correct the heart's rhythm-as soon as possible. VF can happen to anyone-even someone who appears perfectly healthy. Automatic External Defibrillators (AEDs) help save lives.
Related QuestionsHow would I tell if someone is having a heart attack or sudden cardiac arrest?
Frequently Asked Questions - Stop Heart Attack - Defibrillat...The most easy-to-recognize factor is that heart attack patients usually remain conscious while sudden cardiac arrest patients always lose consciousness.
Related QuestionsHow is sudden cardiac arrest treated?
Automated External Defibrillators (AEDs)The only way to effectively treat sudden cardiac arrest (SCA) is with an electrical shock delivered by a defibrillator. Voltage stored by the defibrillator pushes electrical current through the heart by means of the electrodes or paddles placed on the chest. This brief pulse of current halts the chaotic activity of the heart, giving it a chance to start beating again with a normal rhythm. Delivering a shock that returns the heart to a normal rhythm is called defibrillation.
Related QuestionsWhat is the Treatment for Sudden Cardiac Arrest?
DefaultThe only effective treatment for cardiac arrest is an electrical shock to the heart called defibrillation. The electrical current can interrupt ventricular fibrillation (VF) and allow the heart's normal rhythm to regain control. But defibrillation is effective only if it is applied in time - preferably less than four minutes. Until recently, defibrillators were available only in hospitals and some ambulances.
Related QuestionsWhat is sudden cardiac arrest (SCA)?
American Red Cross | Frequently Asked QuestionsSudden cardiac arrest cases are usually due to abnormal heart rhythms called arrhythmias, the vast majority of which are ventricular fibrillation. Ventricular fibrillation is a condition in which the heart's electrical impulses suddenly become chaotic, causing the heart to cease pumping blood effectively. Victims of SCA collapse and quickly lose consciousness, often without warning. Unless a normal heart rhythm is restored, death will follow within a matter of minutes.
Related QuestionsFirst Aid and CPR: AED FAQSudden cardiac arrest cases are usually caused by a deadly heart rhythm called ventricular fibrillation. Ventricular fibrillation causes the heart's electrical impulses to become very chaotic, causing the heart to cease pumping blood effectively. Victims of SCA collapse and quickly lose consciousness, often without warning. Unless a normal heart rhythm is restored, death will follow within a matter of minutes.Related Questions
Allina Medical Transportation | Heart Safe FAQSCA is usually caused by an electrical malfunction of the heart called ventricular fibrillation (VFib) – an ineffective quivering of the heart muscle that makes it unable to pump blood through the body. Once the blood stops circulating, a person quickly loses consciousness and the ability to breathe, and will die without effective treatment. The success of resuscitation drops about 10 percent with each passing minute.Related Questions
How common is sudden cardiac arrest?
Allina Medical Transportation | Heart Safe FAQSCA strikes about 1,000 people a day in the US alone, as many as 1 million people a year worldwide. Tragically, 95 percent of all of them die, making SCA arrest one of the leading causes of death. Sudden cardiac arrest can strike anyone, anywhere, any time, although some medical conditions can increase a person’s risk of suffering cardiac arrest.
Related QuestionsWhat are the symptoms of sudden cardiac arrest?
AEDparts.com :: Your Online Automated External Defibrillator...Some people may experience a racing heartbeat or they may feel 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.
Related QuestionsWhat do I do if I witness sudden cardiac arrest?
AEDparts.com :: Your Online Automated External Defibrillator...If you witness someone experiencing sudden cardiac arrest, dial 911 or your local emergency personnel immediately and initiate CPR. If done properly, CPR can save a person's life, as the procedure keeps blood and oxygen circulating through the body until help arrives. If there is an AED available, the best chance of rescuing the person includes defibrillation with that device. The shorter the time until defibrillation, the greater the chance the person will survive.
Related QuestionsWill an AED always resuscitate someone in cardiac arrest?
AED - Frequently Asked QuestionsThe AED treats only a heart that is in ventricular fibrillation or ventricular tachycardia. In other cardiac arrest situations, the heart does not respond to electric current but needs medications and breathing support instead. Also, AEDs are less successful when the victim has been in cardiac arrest for longer than a few minutes, especially if no CPR was provided.
