What is the correct response for a suspected heart attack?

Having the person lie down and rest is the appropriate response for a suspected heart attack because it minimizes physical exertion, which can exacerbate the condition and lead to increased strain on the heart. By resting, the individual can avoid additional stress on the cardiovascular system, allowing them to remain as calm and stable as possible while awaiting emergency medical services. This position can also help ease discomfort and improve blood flow.

Providing rest can help manage symptoms until professional help arrives, as movement or exertion could lead to severe complications. It's critical that the individual remains calm and comfortable in a safe environment.
