The heart is a complex mechanism, so sometimes it is possible to detect violations in its work only if it is studied for a long time. However, a person can not spend days under the supervision of doctors for permanent measurements. Fortunately, this problem was solved by the biophysicist Norman Holter, whose method allowed to measure the heart readings for several days.

For continuous registration of the patient's electrocardiogram, electrodes are fixed on his body, the indications of which are fixed on a portable recorder device.

A person with a Holter device installed continues to lead a habitual way of life, but should always have a diary to keep records of cases of deterioration of well-being and the circumstances of changes in physical activity or the intake of medicinal substances with a mandatory time sign.

In some cases, the specialist can instruct the patient to perform a series of exercises purposefully to obtain a more accurate result.

Holter mounting is indicated in case of complaints about palpitation, arrhythmia and fainting. In this case, the absence of symptoms during the measurement period does not guarantee the absence of violations, so the patient needs to conduct additional consultations with the doctor, which, if necessary, will give direction to other measurements.

Since during the study period the device accumulates a large amount of information, a thorough and long analysis is required. According to the results, a specialist can identify the presence and give recommendations for the prevention and treatment of arrhythmia attacks, conduction disorders of the heart and episodes of ischemia.
