An EKG exam (electrocardiogram) is a test that records the electrical activity of the heart. Standard 12 lead EKG exams are available 7 days a week by technologists. A computerized report is printed on-site and left at the facility upon completion of the exam. When requested, the EKG can be interpreted by a Board Certified Cardiologist.
