Holter ECG decides on the heart

When a person has any heart problems, he turned for help to a cardiologist.Doctor, to evaluate the health situation of the heart muscle, conducts electrocardiography.

But ECG reveals not all the problems, because it gives a momentary "picture.For example, if the patient has from time to time there are attacks of arrhythmia, but during a visit to the doctor heart will work fine, no abnormalities on ECG will not.In order to detect abnormalities that are not visible at the time of recording ECG, Holter ECG is used.

What Halter?

This is a portable medical device that is attached to the patient's body and using electrodes within twenty-four hours registers electrocardiogram and blood pressure.ECG Holter Named in honor of the inventor of the device - scientist biophysicist Norman Holter.This American researcher has developed and first applied the technique of daily monitoring of the heart in 1961.Analyzing the data in the study, cardiologist can identify violations.But in order to be objective pic

ture of monitoring, the patient needs during the day lead a normal life: go to work, walk, play sports.

In this case the doctor will ask the patient to keep a diary, which will mark the periods of rest, motor activity, emotional stress, eating and medications.In the case of pain, it is necessary to note their nature, duration, time and causes.In some cases, the study can be carried out for two, three and sometimes seven days.

When using Holter ECG?

indications for Holter are the patient's complaints of pain in the heart of unknown origin, dizziness, heart palpitations, loss of consciousness.Cardiologist may prescribe Holter ECG to detect the presence of dangerous arrhythmias, if the patient has had a myocardial infarction, there are hypertrophic cardiomyopathy, or suspected coronary heart disease.

Halter used when you need to evaluate the effectiveness of pacemaker or after antiarrhythmic treatment.When Norman Holter only made his invention, the device weighed 40 kilograms, and the patient was wearing a transmitter in a backpack on his back.Cardiogram record and process a stationary receiver.Modern device for Holter ECG weighs about 500 grams and is small in size, but in spite of this, it may interfere with the patient during sleep.In addition, holter - an expensive complicated electronic device to be careful with him, protected from vibration and shock from the impact of high and low temperatures.Halter can not be wet, so the patient at the time of the study have to give up taking a bath and shower.

Holter monitoring of heart function is effective if within twenty-four hours episodes occur deterioration of the patient, otherwise you need to use additional methods of investigation.
