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.
Initial symptoms may include heart asystole and respiratory arrest. [1] While the asystole may spontaneously resolve fairly rapidly, the respiratory arrest is typically more prolonged. [1] Other symptoms may include burns and blunt injuries. [1] Of those who survive, about 75% have ongoing health problems as a result, such as cataracts and ...
Asystole is the most serious form of cardiac arrest and is usually irreversible. Also referred to as cardiac flatline , asystole is the state of total cessation of electrical activity from the heart , which means no tissue contraction from the heart muscle and therefore no blood flow to the rest of the body.
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 in drowning usually presents as asystole or pulseless electrical activity. Ventricular fibrillation is more likely to be associated with complications of pre-existing coronary artery disease, severe hypothermia, or the use of epinephrine or norepinephrine .
A cardiac flatline is also called asystole. It can possibly be generated by malfunction of the electrocardiography device, but it is recommended to first rule out true asystole because of the emergence of such condition. Definition: A cardiac flatline is referred to as asystole. It can be identified by using an ECG/EKG (electrocardiogram) test.
One common symptom of respiratory arrest is cyanosis, a bluish discoloration of the skin resulting from an inadequate amount of oxygen in the blood. If respiratory arrest remains without any treatment, cardiac arrest will occur within minutes of hypoxemia, hypercapnia or both. At this point, patients will be unconscious or about to become ...
Cardiac symptoms of heart failure include chest pain/pressure and palpitations.Common noncardiac signs and symptoms of heart failure include loss of appetite, nausea, weight loss, bloating, fatigue, weakness, low urine output, waking up at night to urinate, and cerebral symptoms of varying severity, ranging from anxiety to memory impairment and confusion.
