What You Should Know About Cardiac Arrest

Cardiac arrest is a medical emergency in which the heart suddenly and unexpectedly stops beating. Blood ceases to flow through the body, and without artificial assistance, death soon follows. Unless it’s treated almost immediately, cardiac arrest is almost always fatal. Fortunately, there are relatively few instances of this condition occurring among healthy adults. However, when it does happen, it’s essential that you take appropriate action quickly in order to increase the chances of survival. Read on for a brief guide about what you should know about cardiac arrest.

Who Can Experience Cardiac Arrest?

Anyone can experience cardiac arrest, but some people are at a higher risk, including: People who have experienced a heart attack or stroke People with severe or poorly controlled heart or blood vessel disease People with certain types of abnormal heart rhythms (arrhythmias) People who have had recent surgery or other procedures that put pressure on the large blood vessels in the chest People who are very overweight or have a history of weight fluctuations People who have a very low blood sugar level People who are taking certain medications People who are dehydrated People who have high blood pressure People who have low blood potassium levels
