The underlying causes of sudden cardiac arrest can result from cardiac and non-cardiac etiologies. The most common underlying causes are different, depending on the patient's age. Common cardiac causes include coronary artery disease, non-atherosclerotic coronary artery abnormalities, structural heart damage, and inherited arrhythmias. Common ...
Cardiac arrest results from electrical disturbances that cause the heart to suddenly stop beating the way it should. In cardiac arrest, death can result quickly if steps aren’t taken right away.
For people with pre-existing cardiovascular disease, the additional workload can result in myocardial infarction and/or acute heart failure, which ultimately may lead to a cardiac arrest. A vagal response to an extreme stimulus as this one, may, in very rare cases, render per se a cardiac arrest. Hypothermia and extreme stress can both ...

“While it is always alarming when it happens, sudden cardiac arrest in young people is not that uncommon,” Panhwar says, noting that generally the rates of sudden cardiac arrest range from 1 ...
With the advent of these strategies, cardiac arrest came to be called clinical death rather than simply death, to reflect the possibility of post-arrest resuscitation. At the onset of clinical death, consciousness is lost within several seconds, and in dogs, measurable brain activity has been measured to stop within 20 to 40 seconds. [2]
Cardiac arrest happens when the heart’s electrical system malfunctions and the heart’s pumping stops. It can be caused by an arrhythmia, which is an irregular heart rhythm, or other conditions.
Sudden arrhythmic death syndrome (SADS) is a sudden unexpected death of adolescents and adults caused by a cardiac arrest. However, the exact cause of the cardiac arrest, and thus the exact cause of death, is unknown. These deaths occur mainly during sleep or at rest. [7] One type of conduction defect known as Brugada syndrome can be ...
