Until it happens to us or someone we love, most don’t know the difference between a heart attack and a sudden cardiac arrest. You’re definitely not the first to assume a heart attack and sudden cardiac are interchangeable terms.
But when it comes to something that causes around 10% of all deaths in Australia each year (approximately 30,000 Australians die of sudden cardiac arrest each year), we really should be as informed as possible to ensure we’re doing everything possible to help save lives.
So What Is the Key Difference Between a Heart Attack and a Sudden Cardiac Arrest?
The main difference is the cause. A heart attack is caused by a blockage of the blood flow to the heart whereas sudden cardiac arrest is caused by a malfunction of the electrical impulses that go to the heart, stopping it from beating.
Many people believe what happens in a heart attack is that the heart stops beating, but this isn’t always the case. A blockage does cause pain and severe symptoms, but it won’t usually cause swift death the way a sudden cardiac arrest can.
What Is More Serious?
A sudden cardiac arrest is sadly much more likely to be fatal regarding mortality rates. This is mainly because of the short time frame involved – death can happen in minutes. When it comes to a heart attack, it can take hours or days for the symptoms to progress to a point where it is deadly.
The reasons a heart stops beating suddenly can be wide and varied, but one thing is common – bystanders must act quickly to ensure the best possible chance of survival.
