What does an EKG tell you about your heart?

Can an EKG detect a heart attack?

The EKG and a positive sign in the blood test will help the physician diagnose the heart attack. An EKG shows the electrical activity generated by the heart. When there are changes in the electrical complexes, an EKG can show your doctor if the changes are indicative of an acute myocardial infarction (heart attack).
