One of the most dreaded diseases of all time is a heart attack. As everything is mutating, so is the type of heart attack. Have you heard of cardiac arrest? What happens in a cardiac arrest? Is a cardiac arrest different from a heart attack?

This is Now You Know and, in this video, we are going to tell you what is a cardiac arrest?

1. Cardiac arrest is different and much severe from heart failure. The beating rhythm of the heart is disturbed in an arrest causing the barred supply of blood to the brain and other vital organs. This causes multiple organ failure and ultimately loss of pulse.

2. Cardiac arrest is generally a series of attacks. In the heart's regular attempts to regain the original rhythm, the electrical current of the body keeps fluctuating. This can be understood as a voltage fluctuation in electricity which sometimes ends up fusing the bulb. The heart may get ruptured after several attempts to regain the original rhythm.

3. Cardiac arrest needs immediate treatment. If the patient is not treated with first aid like CPR which is Cardiopulmonary Resuscitation that primarily includes pumping the chest of the patient and giving artificial breath through the mouth, the event can prove to be fatal. Also, the patient needs to be treated with life saving medications as soon as possible to restore the functioning of the heart and other organs.

4. The most commonly cardiac arrest occurs due to V-fib which is ventricular fibrillation where the lower 2 chambers of the heart do not function properly disrupting the supply of oxygenated blood to the heart muscles.

5. As a result of this situation, there is no or very little supply of blood to the brain and other organs and can lead to sudden death if not treated immediately.
