Yes. An EKG can detect a heart attack by looking for characteristic changes in the electrical signals of your heart. These changes can sometimes be seen up to several days before a heart attack occurs, which is why it's important to get regular EKGs if you have risk factors for heart disease.
If you think you may be having a heart attack, it's important to call 9-1-1 immediately. Do not wait to see if the symptoms go away – every minute counts when it comes to treating a heart attack.
