[Long-term ECG analysis systems. Comparison of current methods].

Holter monitoring is now standard practice in the internal medical departments of many hospitals, and in doctors' offices. This has led to an increase in the number of companies producing Holter monitoring equipment over the last few years. The wide range of equipment manufacturers can be divided into three categories according to the principles they use in analysing the ECG. The continuous recording system may currently considered standard state of the art in Holter monitoring, since it provides the doctor with the most detailed information about his patient. Furthermore, it is this type of system which lends itself most readily to the incorporation of new hardware and software in this rapidly advancing technological sector.
