Question

Quizplus · Accepted Answer

Persistent chest pain radiating to the left arm, pallor and a rapid, weak pulse are typical early signs or symptoms of myocardial infarction. A substernal pain that lasts only briefly and radiates to the right arm with labored breathing is not as specific to a heart attack. Bradycardia, increased blood pressure, and severe dyspnea, as well as flushed face, rapid respirations, left-side weakness, and numbness are not typical early signs or symptoms of a heart attack.
