Heart Attacks and Cardiac Arrests
What is a cardiac arrest and how is it different to a heart attack?
People often use these terms interchangeably, but they are not synonyms.
A heart attack is when blood flow to the heart is blocked , and sudden cardiac arrest is when the heart malfunctions and suddenly stops beating unexpectedly.
A heart attack is a “ circulation ” problem and sudden cardiac arrest is an “ electrical ” problem.
These two distinct heart conditions are linked. Sudden cardiac arrest can occur after a heart attack, or during recovery. Heart attacks increase the risk for sudden cardiac arrest and are a common cause of them.
