You die: Once you die you will not have symptoms unless somebody saves your life with cpr. Heart disease is from smoking, high cholesterol, diabetes, high blood pressure, and family history.

A 34-year-old member asked:

How can you tell when someone goes into cardiac arrest?

No pulse: Cardiac arrest as the name implies is when the heart stops. When your heart stops beating, blood carrying oxygen does not flow to your body and brain. The body ceases all functions (you stop breathing, you are unconscious, the skin turns pale or blue). The best way to tell if someone is in cardiac arrest is to use a heart monitor (like carried by ems personel) to monitor activity of the heart.

What's the first thing to do if you see someone go into cardiac arrest?

Chest compressions: During cardiac arrest the heart is no longer able to effectively pump blood to the rest of the body. As a result, the brain does not receive enough oxygen which causes the patient to "pass out" and become unresponsive.

Yes: During a cardiac arrest, there is not blood flow, and thus oxygen to the brain. Even is someone survies, they may have brain damage. At times it can be minor, but may have an affect on someones memory, congnition, personality.

How common is it to survive a cardiac arrest?

Dr. Christopher Dowd

Not common: Unfortunately, uncommon. Hard to say exactly, & depends somewhat on what kind of cardiac arrest, what other problems the person has, how long before care, etc. Generally though, for out-of-hospital arrests, less than 20% survive long enough to be discharged from the hospital. Also concerning is how often cardiac arrest is the 1st sign of underlying CAD (plaque in vessels). See a proactive doctor!

What causes cardiac arrest?

Dr. William Goldsmith
Specializes in Critical Care
Many things: Cardiac arrest can be caused by many problems with the heart. The most common is a heart attach which can cause fatally abnormal rhythms when the heart is starved for oxygen. Arrests can also occur from abnormalities in the electrical system of the heart; from drugs or toxins; and from abnormalities of electrolytes particularly high and low potassium.
