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

When considering the signs of a heart attack, it's important to understand the typical symptoms associated with this medical emergency. Chest pain, nausea or vomiting, and difficulty breathing are commonly recognized signs of a heart attack.

Chest pain often manifests as pressure, tightness, or a squeezing sensation in the center or left side of the chest, while nausea and vomiting can occur as a response to the stress the body experiences during a heart attack. Difficulty breathing may result from the heart's reduced ability to function effectively, leading to inadequate blood flow and oxygen supply to the body.

On the other hand, a severe headache is generally not a typical symptom of a heart attack. While headaches can indicate other health issues, they are not associated with the cardiac symptoms that are critical for immediate recognition and response in emergency situations. Understanding these distinctions is essential for first responders and officers trained in first aid, as identifying the signs accurately is vital for timely treatment.
