Which of the following is NOT a sign of a heart attack?

Slurred speech is not typically recognized as a sign of a heart attack. Heart attack symptoms primarily relate to issues with the heart, such as chest pain or discomfort, which may also radiate to the arm, jaw, or back. Other symptoms like dizziness or lightheadedness may occur as a result of insufficient blood flow or other related factors during a heart attack, but they are still closely tied to heart function.

On the other hand, slurred speech is more indicative of a potential stroke or neurological issue rather than a cardiovascular one. Understanding the specific signs of a heart attack helps individuals to correctly identify and respond to cardiac emergencies effectively.
