BOSTON & WASHINGTON, Apr 30, 2012 (BUSINESS WIRE) - Massachusetts Governor Deval Patrick has proclaimed May to be Cardiac Arrhythmia Awareness Month, calling attention to the need for greater public awareness throughout the Commonwealth about two serious heart rhythm conditions, atrial fibrillation (also known as AF or AFib) and sudden cardiac arrest (also known as SCA). (stopafib.org)
Specifically, our research shows that there is a widespread lack of understanding about sudden cardiac arrest and atrial fibrillation, which can lead people to overlook or miss warning signs while the conditions are still treatable. (stopafib.org)
These pulses can normalize the heartbeat to prevent sudden cardiac arrest and death. (nih.gov)
These patients are at high risk for sudden cardiac arrest but have not yet had an episode. (nih.gov)
Treatment is required for cardiac arrhythmias only if the arrhythmia causes serious symptoms, such as dizziness, chest pain, or fainting or if it increases risk for heart failure , stroke or sudden cardiac arrest . (apollohospitals.com)
Some people may experience symptoms beforehand, such as chest pain, heart palpitations, shortness of breath and weakness-but sudden cardiac arrest may occur without warning. (sharecare.com)
More than 350,000 deaths caused by sudden cardiac arrest occur outside of a hospital setting in the U.S. every year. (sharecare.com)

In adults, most cases of cardiac arrest are due to coronary heart disease (narrowing of the vessels that bring blood to the heart), which causes a heart attack. (kidshealth.org)
Very rarely, a young athlete can go into cardiac arrest while playing sports. (kidshealth.org)
How Is Cardiac Arrest Diagnosed? (kidshealth.org)

Can Cardiac Arrest Be Prevented? (kidshealth.org)
Cardiac arrest can't always be prevented. (kidshealth.org)
Cardiac arrest occurs when your heart stops pumping suddenly. (sharecare.com)
Unlike a heart attack, which occurs when the blood flow that supplies the heart with oxygen is blocked, cardiac arrest occurs when the heart's electrical system malfunctions. (sharecare.com)
Cardiac arrest could happen for a variety of reasons, including a heart attack. (sharecare.com)
But atrial arrhythmias that start in the heart's upper champers, such as atrial fibrillation (AFib), may increase the risk for cardiac arrest. (sharecare.com)
This could trigger cardiac arrest. (sharecare.com)
Another arrhythmia which may, in certain cases, be linked to cardiac arrest is called ventricular tachycardia (VT) or V-tach. (sharecare.com)
In extreme cases, this could lead to cardiac arrest. (sharecare.com)
High blood pressure, high cholesterol, diabetes, smoking and obesity are all major risk factors for heart disease, which increases the risk for cardiac arrest, Prager points out. (sharecare.com)
Other cardiac arrest risk factors include having a personal or family history of arrhythmias or inherited diseases associated with abnormal heart rhythms, including Wolff-Parkinson-White syndrome and Long QT syndrome. (sharecare.com)
Cardiac arrest is an emergency that requires immediate medical attention. (sharecare.com)
The hope is that if someone goes into cardiac arrest, we can shock them out of it," he explains. (sharecare.com)
Fast arrhythmias may also cause children or adolescents to pass out (syncope) or, in very rare circumstances, a cardiac arrest. (cincinnatichildrens.org)
MAs may be manifested either in hemodynamic collapse or in cardiac arrest: The sudden loss of effective blood flow due to atrial fibrillation (AF) with rapid VT leads to hemodynamic collapse, and VT and VF result in cardiac arrest necessitating CPR or electric defibrillation. (medscape.com)
