What is Cardiac arrest
What are the signs of a cardiac arrest?
There are usually no symptoms before a cardiac arrest and without immediate treatment , it will be fatal. If someone is in cardiac arrest.
- they won’t be conscious
- they won’t be responsive
- they won’t be breathing, or breathing normally.
What causes a cardiac arrest?
The most common cause of a cardiac arrest is life fearing abnormal heart rhythm so called as ventricular fibrillation (VF).
Ventricular fibrillation is said to happen when the electrical activity of your heart becomes so chaotic that the heart is said to stops pumping and quivers or ‘fibrillates’ instead.
Heart-related causes of cardiac arrest:
- coronary heart disease
- heart attack
- cardiomyopathy and some inherited heart conditions
- congenital heart disease
- heart valve disease
- acute myocarditis (inflammation of the heart muscle)
- heart conduction disorders that make you more likely to experience abnormal heart rhythms, such as Long QT syndrome.
Other causes of cardiac arrest:
- drug overdose
- severe haemorrhage – losing a large amount of blood
Can you recover from a cardiac arrest?
VF will be sometimes corrected by giving an electrical shock through chest wall by using device so called as defibrillator. This is said to be done by member of public, emergency services or at hospital.
Immediate CPR is said to keep oxygen in circulating around the body until a defibrillator can be used and/or until the emergency services arrive.
What’s the difference between a cardiac arrest and a heart attack?
People often think about a cardiac arrest and heart attack are on the same thing but it isn’t true.
A heart attack happens when blood supplying at the heart muscle is decreased because of a clot at one of the coronary arteries. This due to the cause chest pain, although symptoms which might be less severe, and can permanently damage the heart. The heart is still sending blood to the body and person is said to be breathing and conscious. Person who have a heart attack is said to have a high risk of experiencing in a cardiac arrest.
A cardiac arrest is said to occur when the heart immediately stops pumping blood around the body, often due the problem with the electrical signals to the heart muscle. Someone is having a cardiac arrest will suddenly collapse and will stop breathing.
Both a heart attack and a cardiac arrest are life-threatening medical emergencies – call 108 immediately if you witness someone having a cardiac arrest or think you or someone you’re with is having a heart attack.
