Cardiac arrest may be a sudden loss of blood flow resulting from the failure of the guts to pump effectively. Signs include loss of consciousness and abnormal or absent breathing. Some individuals may experience pain, shortness of breath, or nausea before asystole. If not treated within minutes, it typically results in death. The most common cause of
cardiac arrest is
coronary artery disease. Less common causes include major blood loss, lack of oxygen, very low potassium, coronary failure, and intense workout. A number of inherited disorders can also increase the
danger including long QT syndrome. The initial cardiac rhythm is the most frequent fibrillation. The diagnosis is confirmed by finding no pulse. While asystole could also be caused by
memory attack or coronary failure, these aren't an equivalent.
