No. Although people often mistaken with the heart stop for a heart attack, they do not match. A heart attack can cause cardiac arrest, but these are different conditions.
The heart attack is caused by a blockage of blood flow to a part of the heart muscle, usually blood. As a result, the heart muscles are damaged. A heart attack is a serious condition and can even become deadly.
The heart delay, on the other hand, is caused when the electric system of the heart malfunction. The heart ceases to fight properly, and its ability to pump blood suddenly stops.
