Unlike cardiac arrest, a heart attack is a circulation problem. When circulation is blocked or cut off in some way and blood is no longer supplied to the heart muscle, this can damage that muscle ...
Cardiac arrest (also known as sudden cardiac arrest [SCA] [11]) is when the heart suddenly and unexpectedly stops beating. [ 12 ] [ 1 ] When the heart stops beating, blood cannot properly circulate around the body and the blood flow to the brain and other organs is decreased.
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 ]
Traumatic cardiac arrest is a complex form of cardiac arrest often derailing from advanced cardiac life support in the sense that the emergency team must first establish the cause of the traumatic arrest and reverse these effects, for example hypovolemia and haemorrhagic shock due to a penetrating injury.
Before cardiac arrest, the body is in a state of homeostasis. Arterial blood circulates appropriately through the body, supplying oxygen to tissues while the venous blood collects metabolic waste products to be utilized elsewhere and/or eliminated from the body. However, during cardiac arrest, the body is in circulatory and pulmonary arrest ...
End organ damage is severe impairment of major body organs due to systemic disease. Commonly this is referred to in diabetes , high blood pressure , or states of low blood pressure or low blood volume. [ 1 ]
Coronary ischemia, myocardial ischemia, [1] or cardiac ischemia, [2] is a medical term for abnormally reduced blood flow in the coronary circulation through the coronary arteries. [3] Coronary ischemia is linked to heart disease , and heart attacks . [ 4 ]
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 ...
