Sudden Cardiac Death
Lindsay Hoke & Noah Kirby

Sudden Cardiac Death is a sudden, unexpected death caused by loss of heart function, also known as sudden cardiac arrest.

Sudden Cardiac Death occurs by the occurrence of sudden cardiac arrest.  This occurs when the electrical system to the heart malfunction and suddenly becomes very irregular. The heart beats dangerously fast. The ventricles may flutter or quiver *ventricular fibrillation), and blood is not delivered to the body. In the first few minutes, the greatest concern is that blood flow to the brain will be reduced so fast and so much that a person will lose consciousness. Unless emergency treatment is begun immediately, it results in sudden cardiac death.

Symptoms of sudden cardiac death: some people may experience symptoms of sudden cardiac arrest, such as a racing heartbeat or feeling dizzy, alerting them that a potientally dangerous heart rhythm has started. But, in more than half of the cases, there are no symptoms.

Some diagnostic tests for SCD include the electrocardiogram, an echocardiography, a MUGA test, a cardiac MRI, a cardiac catheterization, a electrophysiology study, or blood tests.

The most common diagnostic test is the EKG, or electrocardiogram. An EKG is a simple, painless test that records and detects the patient's heart and heart's electrical activity. It shows how fast the heart is beating, and if the rhythm is steady or irregular. Also, it records the strength and timing of the electrical signals as they pass through each part of the heart.

Sudden cardiac death is the largest cause of natural death in the U.S.

It causes about 325,000 adult deaths in the U.S. each year. It is responsible for half of all heart disease deaths.

Following a healthy lifestyle can help you lower your risk for SCD, CHD, as well as other heart problems. This includes eating healthy, and getting exercise.

Risk factors/complications include.. a personal or family history of SCA (sudden cardiac arrest) or inherited disorders that make you prone to arrhythmias, a personal history of arrhythmias, a heart attack, heart failure, and/or drug/alcohol abuse.

Really, the only treatment option for sudden cardiac death is emergency treatment.

A person who is having sudden cardiac arrest needs to be treated with a defibrillator right away. A defibrillator sends an electric shock to the heart which restores a normal rhythm to a heart that has stopped beating. But, to work, it must be done within minutes of sudden cardiac arrest.


Because, if not, it results in sudden cardiac death.
