There are numerous reasons for having an EKG performed. However, three common reasons that a person would get an EKG include the following: • Determine a person’s heart function during a routine physical exam or before a surgical procedure • Evaluate common symptoms of heart conditions, such as chest pain, dizziness, extreme fatigue, fainting, or shortness of breath (dyspnea) • See how well the heart is functioning after treatment for a heart condition or how well an implanted pacemaker is working
