It records the electrical activity of the heart continuously over 24 hours or longer while you are away from the doctor's office. A standard or "resting" ECG is one of the simplest and fastest tests used to evaluate the heart. Electrodes (small, plastic patches that stick to the skin) are placed at certain points on the chest and abdomen. The electrodes are connected to an ECG machine by wires. Then, the electrical activity of the heart can be measured, recorded, and printed. No electricity is sent into the body. Natural electrical impulses coordinate contractions of the different parts of the heart. This keeps blood flowing the way it should. An ECG records these impulses to show how fast the heart is beating, the rhythm of the heart beats (steady or irregular), and the strength and timing of the electrical impulses. Changes in an ECG can be a sign of many heart-related conditions. It takes about 10 minutes for the electrodes and recorder to be fitted. You then go and do what you normally do over the next 24-48 hours. You wear the recorder when asleep in bed too. (However, you should not have a bath or shower, as the recorder should not get wet.) You will be given a diary to record the times when you develop any symptoms - such as the feeling of a 'thumping heart' (palpitations). The ECG tracing is analysed at the end of the test. But, any times you record when you had symptoms will be most carefully analysed to see if you had an abnormal heart rate or rhythm (arrhythmia) to account for the symptoms. A doctor may ask you to do some activities which have previously brought on symptoms, to try to provoke the same symptoms. There are some variations in the equipment that may be used: On some recorders, you press a button to mark the time whenever symptoms occur. Some recorders activate automatically only if your heart rate or rhythm is abnormal. With some recorders you send the ECG tracing for analysis down the phone line. Some recorders are worn for longer periods. These are called 'event' monitors. They record only when you switch them on during an 'event' such as a bout of palpitations.
