Electromyography (EMG) is a general term meaning, the recording of the electrical activity of nerve and muscle. EMG is a diagnostic test used to assess the function of nerves and muscles. You may be sent for an EMG test if you are experiencing numbness, tingling, weakness, or pain. The test may take from 45 minutes to 1.5 hours depending on what your doctor has ordered.
ECG (EKG) (electrocardiogram): A record of the electrical impulses that immediately precede contraction of the heart muscle. The waves produced are known as the P,Q,R,S and T waves. An ECG is a useful means of diagnosing disorders of the heart, many of which produce deviations from normal electrical patterns. Electrocardiography causes no discomfort. Electrodes connected to a recording machine are applied to the chest, wrists, and ankles. The machine displays the electrical activity in the heart as a trace on a moving graph or on a screen. An ECG can be taken at home; a 24-hour record can be obtained from a tape recorder worn by the patient.
