General information about the heart for patients, their family members, and concerned laymen

  The Arrhythmias Section Contents
Holter Monitoring
     Ambulatory ECG (Holter) recording is discussed in detail here. Briefly, you will be lent a small box that records your electrocardiogram continuously for 24 or more hours. The box is attached to your body with wires that connect to three little electrodes on the skin of your chest. The skin is cleaned thoroughly before the electrodes are attached to make sure they can record well. You will also be given a diary card, on which you should write the time and description of any symptoms or other significant activities. After you return the box, the recording will be played back into a special analysis machine, which a trained technologist uses to prepare a summary with appropriate rhythm samples for your physician.

Often, people don't have their symptoms while they are wearing the recording box. In these cases, the physician may recommend repeating the recording several times, sometimes several days in a row.

Event Recording
     Event (transtelephonic and cellular) recording is discussed in more detail here. Briefly, you will be given a small device that you can carry in a pocket or in a purse. You will also be given a telephone number to call. When you have your symptoms, you attach the device to your body temporarily, usually by putting on bracelets or pressing electrodes on the device against your chest. You then press a button on the device to start a recording of your heart rhythm that lasts a variable length of time up to a minute or so. Then, you call the telephone number to transmit the rhythm recording over the telephone to a receiving station. The receiving station is able to print out a copy of the rhythm you recorded. In many cases, a trained technologist will interpret the rhythm immediately, and call an ambulance near your home if necessary.

Usually, event recording devices are lent to the patient for two to four weeks at a time. If the symptoms occur frequently, of course, the physician may get enough information within a few days to make a diagnosis. The event recording device can be returned as soon as the diagnosis is made.
