However, this type of screening is expensive and can produce false-positive results — indications that an abnormality or disease is present when it isn't — which can cause unnecessary worry and additional tests. It's not clear that routine exams given before athletes are cleared to play competitive sports can prevent sudden cardiac death.
However, they might help identify some who are at increased risk. For anyone with a family history or risk factors for conditions that cause sudden cardiac death, further screening is recommended. Repeat screening of family members is recommended over time, even if the first heart evaluation was normal.
If you're at risk of sudden cardiac death, talk to your doctor about physical activity. Whether you can participate in exercise or sports depends on your condition. For some disorders, such as hypertrophic cardiomyopathy, it's often recommended that you avoid most competitive sports and that if you have an ICD, you should avoid impact sports.
But this doesn't mean you need to avoid exercise. Talk to your doctor about restrictions on your activity. There is a problem with information submitted for this request.

Products and services. Sudden death in young people: Heart problems often blamed Sudden death in young people is rare, but those at risk can take precautions. These include:. When sudden cardiac arrest occurs, reduced blood flow to your brain causes unconsciousness. If your heart rhythm doesn't rapidly return to normal, brain damage occurs and death results. Survivors of cardiac arrest might show signs of brain damage. Reduce your risk of sudden cardiac arrest by getting regular checkups, being screened for heart disease and living a heart-healthy lifestyle.

If you are at high risk for SCA, your provider may refer you to a cardiologist, a doctor who specializes in heart diseases. The cardiologist may ask you to get various heart health tests to see how well you heart is working. He or she will work with you to decide whether you need treatment to prevent SCA. SCA is an emergency. A person having SCA needs to be treated with a defibrillator right away.
A defibrillator is a 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, it needs to be done within minutes of the SCA.
Most police officers, emergency medical technicians, and other first responders are trained and equipped to use a defibrillator. Call right away if someone has signs or symptoms of SCA. The sooner you call for help, the sooner lifesaving treatment can begin. Many public places such as schools, businesses, and airports have automated external defibrillators AEDs. AEDs are special defibrillators that untrained people can use if they think that someone has had SCA.
AEDS are programmed to give an electric shock if they detect a dangerous arrhythmia. This prevents giving a shock to someone who may have fainted but isn't having SCA. If you see someone who you think has had SCA, you should give cardiopulmonary resuscitation CPR until defibrillation can be done. Ask your cardiologist to help you decide whether having an AED in your home might help you.
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. They will also try to find out what caused your SCA. If you're diagnosed with coronary artery disease, you may have an angioplasty or coronary artery bypass surgery. These procedures help restore blood flow through narrowed or blocked coronary arteries.
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. You may be able to lower your risk of SCA by following a heart-healthy lifestyle. If you have coronary artery disease or another heart disease, treating that disease can also lower your risk of SCA.
