Arrhythmogenic Right Ventricular Dysplasia (ARVD): when the right ventricle (bottom chamber) wall heart muscle is replaced with fatty-fibrous tissue; this leads to it being stretched and weakened, causing an enlarged right ventricle and decreased effective pumping ability.
Coronary Artery Abnormalities (CAA): the arteries which supply the heart with oxygenated blood are malformed; during exercise, the heart does not receive the oxygenated blood needed, leading to a lethal rhythm called ventricular fibrillation.
Dilated Cardiomyopathy (DCM): when the heart muscle is stretched and enlarged making it hard for the heart to function properly; most common form of cardiomyopathy
Hypertrophic Cardiomyopathy (HCM): when the heart muscle becomes to thick to properly pump the blood through; can lead to blockage of blood flow out of the heart and lethal rhythms; second most common type of cardiomyopathy.
Kawasaki Disease: caused by an inflammation of the blood vessels in the body, including those in the heart; this can lead to damage and further complications in the future.
Marfan Syndrome: inherited abnormality of the connective tissues of the body; aorta (largest artery in the body) can become weak and rupture; usually characterized by long legs, toes, arms and fingers.
Mitral Valve Prolapse (MVP): when the valve between the left atrium (upper chamber) and left ventricle (lower chamber) do not close properly, allowing blood to flow backwards; this can lead to arrhythmias.
Myocarditis: inflammation of the heart muscle due to a virus, bacteria or fungus causing a weakening of the walls, decrease in pumping action and decrease in ability to oxygenated blood to the rest of the heart and body.

Brugada Syndrome: abnormality in the channels which direct the electrical currents in the heart, that could lead to a deadly rhythm called ventricular fibrillation.
Catecholaminergic Polymorphic Ventricular Tachyardia (CPVT): the heart rate increases due to physical or stressed induced situation, which can lead to ventricular tachycardia and then SCA.
Long Q-T Syndrome: when the heart's electrical system takes alonger than normal time to prepare for the next heartbeat; this can lead to a chaotic heart rhythm.
Wolff-Parkinson-White Syndrome (WPW): an extra electrical pathway from the atria (top chamber) to the ventricle (bottom chamber) is created and can lead to excessively fast heart rates.
AEDs (Automatic External Defibrillators)
Sudden Cardiac Arrest (SCA) is when the electrical system of the heart does not function properly leading to the heart not pumping blood to vital organs and the rest of the body. When this occurs, the victim loses consciousness and/or has seizure like activity. If untreated within minutes of occurring, it leads to Sudden Cardiac Death (SCD).
An automated external defibrillator (AED) is a portable, user-friendly electronic medical device that can analyze and diagnose potentially life-threatening heart rhythms. If the AED detects a heart problem that may respond positively to an electric shock, it permits a shock to be delivered to restore a normal heart rhythm. AEDs provide simple audio and visual instructions, designed for easy use. AEDs are simplistic in nature, can be used by anyone, have audible prompts, easily accessible where available.
