Electrocardiography and Holter monitoring are among the simplest and most widely available tools for initial heart evaluations. An electrocardiograph test monitors your hearts electrical activity, producing an electrocardiogram (an ECG, or EKG, for short), which is a graph of your heart rhythm and blood flow pattern over a certain period of time.
