What are the important signs and symptoms of a heart attack?

Signs and symptoms of a heart attack (myocardial infarction): Persistent central chest pain radiating to the left arm, pallor, and rapid, weak pulse will be the most typical answer, though some of the other symptoms could also occur in myocardial infarction. For example, some have radiation to right arm. breathlessness can occur if myocardial infarction has resulted in left ventricular failure. Bradycardia (slow heart rate) is common in inferior wall myocardial infarction due to occlusion of right coronary artery, supplying the lower part of the heart.
