For your convenience, HRMC Physicians Clinic offers on-site EKG (electrocardiogram) testing to assess and evaluate heart issues. An EKG test records the electrical activity of your heart through small electrode patches attached to the skin of your chest, arms and legs. An EKG may be part of a routine physical exam, or it may be used as a test for heart disease. An EKG can be used to further investigate symptoms related to heart problems.
