It can also be carried out on a sample of hair, skin or bodily tissue. A genetic test is usually done with a simple blood test. How do they test for inherited heart conditions?ДЄn inherited heart condition is usually tested for with a genetic test. The earlier you and your family are tested, the less you risk a family member possibly leaving a heart problem untreated. Some people might not feel ready to be tested after losing a loved one which is understandable, but the tests are usually simple for most people. When this happens, the coroner will usually recommend that family members are tested for inherited heart conditions. SADS is declared if the death is still unexplained after these tests. The coroner will then decide on a cause of death. ask for an assessment by an expert heart pathologist.test for medications or drugs in the body.If the pathologist canвЂ™t find an obvious cause of death, they may do further tests such as: They can offer emotional and practical support during what might be an extremely difficult time for you, and they can be your main point of contact after the death and the post-mortem examination.Дuring the post-mortem examination, a pathologist (a doctor trained in the study of disease) will look for conditions that could have caused the death, such as: If you have recently lost a loved one suddenly, or know someone who has, you may want to contact a bereavement officer at your local hospital. In some cases, this is the only way of telling if someone has an inherited heart condition or if they are at risk of developing one. We can sometimes discover these changes with genetic testingВ for family members, known as cascade testing. Thanks to research, we now know that these conditions are caused by changes (or mutations) in one or more of our genes. arrhythmogenic right ventricular cardiomyopathy (ARVC).

SADS may still be diagnosed because the structural changes are too small to be seen when the heart is examined after death. But there are a few conditions that can cause SADS because of very subtle changes to the heart.

progressive cardiac conduction defect (PCCD).ДЄ condition that causes SADS is undetectable after death because the heart will appear normal.

catecholaminergic polymorphic ventricular tachycardia (CPVT).

Inherited heart conditions are often the cause of SADS if they are left undetected and untreated. Sometimes, the heart condition that causes the arrhythmia can be inherited. It is usually caused by a heart condition that affects the heartвЂ™s electrical system. An arrhythmia usually causes the heart to beat too fast, too slow or irregularly. SADS usually happens when an abnormal heart rhythm, known as an arrhythmia, goes untreated and leads to a cardiac arrest. You may also see sudden arrhythmic death syndrome, or SADS, being called sudden adult death syndrome.ДЇind out more about Sudden Arrhythmic Death Syndrome, what to expect from an inherited heart condition clinic and how you and your family can get support if you know someone who has sadly died suddenly.Дownload Life with Inherited Abnormal Heart Rhythms What causes SADS? Sudden arrhythmic death syndrome affects around 500 people in the UK every year. This is why the cause of the cardiac arrest canвЂ™t be found and SADS might be diagnosed. Your heartвЂ™s rhythm and electrical impulses are no longer there after death, this means an abnormal heart rhythm canвЂ™t be found and the heartвЂ™s structure will appear normal. Some arrhythmias can be dangerous if theyвЂ™re left untreated, they can cause a cardiac arrest. If the electrical impulses go wrong, it can cause an abnormal heart rhythm known as an arrhythmia.

The rhythm of your heart (which controls your heartbeat) is controlled by electrical impulses. This stops your breathing and starves your brain of oxygen. Sudden arrhythmic death syndrome is when someone dies suddenly and unexpectedly from a cardiac arrest, but the cause of the cardiac arrest canвЂ™t be found.ДЄ cardiac arrest is when your heart suddenly stops pumping blood around your body.
