Sudden cardiac arrest SCA is a condition in which the heart suddenly and unexpectedly stops beating. If this happens, blood stops flowing to the brain and other vital organs. SCA usually causes death if it's not treated within minutes. Overview To understand SCA, it helps to understand. The heart has an electrical system that controls the rate and rhythm of the heartbeat. Problems with the heart's electrical system can cause irregular heartbeats called. There are many types of arrhythmias. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. Some arrhythmias can cause the heart to stop pumping blood to the body—these arrhythmias cause SCA. SCA is not the same as a. A heart attack occurs if blood flow to part of the heart muscle is blocked. During a heart attack, the heart usually doesn't suddenly stop beating. SCA, however, may happen after or during recovery from a heart attack. People who have heart disease are at higher risk for SCA. However, SCA can happen in people who appear healthy and have no known heart disease or other risk factors for SCA. Outlook Most people who have SCA die from it—often within minutes. Rapid treatment of SCA with a defibrillator can be lifesaving. A defibrillator is a device that sends an electric shock to the heart to try to restore its normal rhythm. AEDs can be used by bystanders to save the lives of people who are having SCA. These portable devices often are found in public places, such as shopping malls, golf courses, businesses, airports, airplanes, casinos, convention centers, hotels, sports venues, and schools. Ventricular fibrillation v-fib causes most sudden cardiac arrests SCAs. V-fib is a type of. During v-fib, the ventricles the heart's lower chambers don't beat normally. Instead, they quiver very rapidly and irregularly. When this happens, the heart pumps little or no blood to the body. V-fib is fatal if not treated within a few minutes. Other problems with the heart's electrical system also can cause SCA. For example, SCA can occur if the rate of the heart's electrical signals becomes very slow and stops. SCA also can occur if the heart muscle doesn't respond to the heart's electrical signals. Certain diseases and conditions can cause the electrical problems that lead to SCA. Examples include CHD , also called coronary artery disease; severe physical stress; certain inherited disorders; and structural changes in the heart. Several research studies are under way to try to find the exact causes of SCA and how to prevent them. Coronary Heart Disease CHD is a disease in which a waxy substance called plaque plak builds up in the coronary arteries. These arteries supply oxygen-rich blood to your heart muscle. Plaque narrows the arteries and reduces blood flow to your heart muscle. Eventually, an area of plaque can rupture break open. This may cause a blood clot to form on the plaque's surface. A blood clot can partly or fully block the flow of oxygen-rich blood to the portion of heart muscle fed by the artery. During a heart attack, some heart muscle cells die and are replaced with scar tissue. The scar tissue damages the heart's electrical system. As a result, electrical signals may spread abnormally throughout the heart. These changes to the heart increase the risk of dangerous arrhythmias and SCA. CHD seems to cause most cases of SCA in adults. Many of these adults, however, have no signs or symptoms of CHD before having SCA. Physical Stress Certain types of physical stress can cause your heart's electrical system to fail. The hormone adrenaline is released during intense physical activity. This hormone can trigger SCA in people who have heart problems. These minerals play an important role in your heart's electrical signaling. Inherited Disorders A tendency to have arrhythmias runs in some families. This tendency is inherited, which means it's passed from parents to children through the genes. Members of these families may be at higher risk for SCA. An example of an inherited disorder that makes you more likely to have arrhythmias is LQTS. LQTS is a disorder of the heart's electrical activity. Problems with tiny pores on the surface of heart muscle cells cause the disorder. LQTS can cause sudden, uncontrollable, dangerous heart rhythms. People who inherit structural heart problems also may be at higher risk for SCA. These types of problems often are the cause of SCA in children. Structural Changes in the Heart Changes in the heart's normal size or structure may affect its electrical system. Examples of such changes include an enlarged heart due to or advanced heart disease. Heart infections also may cause structural changes in the heart. Men are more likely than women to have SCA. Major Risk Factor The major risk factor for SCA is. Most people who have SCA have some degree of coronary heart disease; however, many people may not know that they have coronary heart disease until SCA occurs. Because of this, doctors and nurses have not detected it. Many people who have SCA also have silent, or undiagnosed, before sudden cardiac arrest happens. Research shows that an ICD reduces the chances of dying from a second SCA. An ICD is surgically placed under the skin in your chest or abdomen. The device has wires with electrodes on the ends that connect to your heart's chambers. The ICD monitors your heartbeat. If the ICD detects a dangerous heart rhythm, it gives an electric shock to restore the heart's normal rhythm. Your doctor may give you medicine to limit irregular heartbeats that can trigger the ICD. Implantable Cardioverter Defibrillator The illustration shows the location of an implantable cardioverter defibrillator in the upper chest. The electrodes are inserted into the heart through a vein. An ICD isn't the same as a. The devices are similar, but they have some differences. Pacemakers give off low-energy electrical pulses. They're often used to treat less dangerous heart rhythms, such as those that occur in the upper chambers of the heart. Most new ICDs work as both pacemakers and ICDs. For People at High Risk for a First Sudden Cardiac Arrest If you have severe CHD , you're at increased risk for SCA. This is especially true if you've recently had a. Your doctor may prescribe a type of medicine called a beta blocker to help lower your risk for SCA. Your doctor also may discuss beginning statin treatment if you have an elevated risk for developing heart disease or having a stroke. Take all medicines regularly, as your doctor prescribes. You should still follow a heart-healthy lifestyle, even if you take medicines to treat your coronary heart disease. Other treatments for coronary heart disease—such as , also known as coronary angioplasty, or —also may lower your risk for SCA. For People Who Have No Known Risk Factors for Sudden Cardiac Arrest CHD seems to be the cause of most SCAs in adults. CHD also is a major risk factor for chest pain or discomfort and heart attack, and it contributes to other heart problems. Following a heart-healthy lifestyle can help you lower your risk for CHD, SCA, and other heart problems. Doctors rarely diagnose SCA with medical tests as it's happening. Instead, SCA often is diagnosed after it happens. Doctors do this by ruling out other causes of a person's sudden collapse. Specialists Involved If you're at high risk for SCA, your doctor may refer you to a cardiologist. This is a doctor who specializes in diagnosing and treating heart diseases and conditions. Your cardiologist will work with you to decide whether you need treatment to prevent SCA. Some cardiologists specialize in problems with the heart's electrical system. These specialists are called cardiac electrophysiologists. Diagnostic Tests and Procedures Doctors use several tests to help detect the factors that put people at risk for SCA. EKG Electrocardiogram An is a simple, painless test that detects and records the heart's electrical activity. The test shows how fast the heart is beating and its rhythm steady or irregular. An EKG also records the strength and timing of electrical signals as they pass through each part of the heart. An EKG can show evidence of heart damage due to CHD. The test also can show signs of a previous or current. Echocardiography Echocardiography, or echo, is a painless test that uses sound waves to create pictures of your heart. The test shows the size and shape of your heart and how well your heart chambers and valves are working. Echo also can identify areas of poor blood flow to the heart, areas of heart muscle that aren't contracting normally, and previous injury to the heart muscle caused by poor blood flow. There are several types of echo, including stress echo. This test is done both before and after a. During this test, you exercise or are given medicine if you're unable to exercise to make your heart work hard and beat fast. Stress echo shows whether you have decreased blood flow to your heart a sign of CHD. MUGA Test or Cardiac MRI A MUGA multiple gated acquisition test shows how well your heart is pumping blood. For this test, a small amount of radioactive substance is injected into a vein and travels to your heart. The substance releases energy, which special cameras outside of your body can detect. The cameras use the energy to create pictures of many parts of your heart. The test creates still and moving pictures of your heart and major blood vessels. Doctors use cardiac MRI to get pictures of the beating heart and to look at the structure and function of the heart. Cardiac Catheterization is a procedure used to diagnose and treat certain heart conditions. A long, thin, flexible tube called a catheter is put into a blood vessel in your arm, groin upper thigh , or neck and threaded to your heart. Through the catheter, your doctor can do diagnostic tests and treatments on your heart. Sometimes dye is put into the catheter. The dye will flow through your bloodstream to your heart. The dye makes your coronary heart arteries visible on x-ray pictures. The dye can show whether plaque has narrowed or blocked any of your coronary arteries. Electrophysiology Study For an electrophysiology study, doctors use cardiac catheterization to record how your heart's electrical system responds to certain medicines and electrical stimulation. This helps your doctor find where the heart's electrical system is damaged. Blood Tests Your doctor may recommend to check the levels of potassium, magnesium, and other chemicals in your blood. These chemicals play an important role in your heart's electrical signaling. Emergency Treatment Sudden cardiac arrest SCA is an emergency. A person having SCA needs to be treated with a defibrillator right away. This device sends an electric shock to the heart. The electric shock can restore a normal rhythm to a heart that's stopped beating. To work well, defibrillation must be done within minutes of SCA. With every minute that passes, the chances of surviving SCA drop rapidly. Police, emergency medical technicians, and other first responders usually are trained and equipped to use a defibrillator. Call 9—1—1 right away if someone has signs or symptoms of SCA. The sooner you call for help, the sooner lifesaving treatment can begin. Automated External Defibrillators AEDs are special defibrillators that untrained bystanders can use. These portable devices often are found in public places, such as shopping malls, golf courses, businesses, airports, airplanes, casinos, convention centers, hotels, sports venues, and schools. AEDs are programmed to give an electric shock if they detect a dangerous , such as ventricular fibrillation. This prevents giving a shock to someone who may have fainted but isn't having SCA. You should give CPR to a person having SCA until defibrillation can be done. People who are at risk for SCA may want to consider having an AED at home. A 2008 study by the National Heart, Lung, and Blood Institute and the National Institutes of Health found that AEDs in the home are safe and effective. Some people feel that placing these devices in homes will save many lives because many SCAs occur at home. Others note that no evidence supports the idea that home-use AEDs save more lives. These people fear that people who have AEDs in their homes will delay calling for help during an emergency. They're also concerned that people who have home-use AEDs will not properly maintain the devices or forget where they are. When considering a home-use AED, talk with your doctor. He or she can help you decide whether having an AED in your home will benefit you. Treatment in a Hospital If you survive SCA, you'll likely be admitted to a hospital for ongoing care and treatment. In the hospital, your medical team will closely watch your heart. They may give you medicines to try to reduce the risk of another SCA. While in the hospital, your medical team will try to find out what caused your SCA. If you're diagnosed with , you may have, also known as coronary angioplasty, or. These procedures help restore blood flow through narrowed or blocked coronary arteries. Often, people who have SCA get a device called an ICD. This small device is surgically placed under the skin in your chest or abdomen. An ICD uses electric pulses or shocks to help control dangerous arrhythmias. For more information, go to.
