How Sudden Cardiac Arrest Differs from a Heart Attack
A recent study suggests warning signs may indicate an underlying heart condition well before this life-threatening event occurs.
When someone has suffered a cardiac arrest or sudden cardiac death, most people assume the person had a heart attack. But sudden cardiac arrest is a very different event. Cardiologists explain that it’s caused by a malfunction of the heart’s electrical system, while a heart attack is caused by a “plumbing problem,” or more specifically, blockage in a coronary artery.
