With the heart not beating anymore, oxygenated blood will no longer be pumped to the brain. This in term will slowly starve to death of oxygen, this, in most cases, is around the three minute mark.

Is cardiac arrest result in myocardial infarction?

Cardiac arrest occurs when the heart stops beating (or arrests). When a myocardial infarction (MI) occurs a portion of the heart either dies or becomes ischemic. Usually arrest wouldn't be due to an MI but if an MI was big enough it would initiate an arrhythmia called fibrillation and the heart would stop pumping blood. This is also called sudden cardiac death. SCD can occur without an MI as well.


Is cardiac arrest painful?

No, because cardiac arrest is when the heart stops; so this means if someone goes into cardiac arrest, he/she will die (unless he/she is saved by medical care/help). You probably mean heart attack. The answer to your question (presuming you mean heart attack) is: Yes. The areas that are painful include: Chest (severe pain), left arm and jaw (note: not all these areas may be in pain during a heart attack). The difference between Heart Attack and Cardiac Arrest: Heart Attack: Occurs when there is a blockage in the coronary (main) arteries of the heart. Cardiac Arrest: Is when the heart stops suddenly.


How long can Cardiac cells can withstand ischemic conditions?

30-40 minutes until irreversible damage occurs.


Cardiac arrest is the same heart attract?

No, they are not the same (I have given the definitions of both below; this should help you know what each is and what is the difference between the two). Heart attack: Is caused when there is a blockage in the main arteries (coronary arteries) of the heart. Cardiac Arrest: occurs when the heart suddenly stops beating. Sorry, but Cardiac Arrest does not usually occur when the heart "suddenly" stops beating. Cardiac arrest is the worst manifestation of cardiac compromise from an acute coronary event. It happens for a number of reasons, for example if a person has had extensive bleeding and there's not enough blood within the body for the heart to pump, or when the pumping action of the heart becomes ineffective. Maybe the electrical impulses have been disrupted or the heart is not responding properly to the electrical impulses and is "twitching", most commonly known as ventricular fibrillation. That's where CPR and Automated External Defibrillation come in. If cardiac arrest occurred when the heart "suddenly stopped beating" CPR and AED's would be mostly ineffective. Time is of essence. CPR needs to be started w/in 10 minutes of the fibrillation attack/cardiac arrest, or chances are it will be too late for resuscitation. Severe brain and heart damage will have occurred by that point. Cardiac arrest victims are sometimes said to have suffered "sudden death" but that means that the patient died within one hour of the onset of the signs and symptoms. In "sudden death" autopsies typically show the patient did not really have an actual cardiac arrest but usually had significant artherosclerotic heart disease

Can someone laugh to death?

Yes, they can. Laughing without breathing properly can cause asphyxiation or cardiac arrest. Laughing uncontrollably can also cause atonia and muscle collapse. However, these cases are extremely rare and occurs about on average once every 30 years.
