Holter monitoring is a method of functional diagnostics, allowing to carry out daily monitoring of the electrocardiogram. ECG recording is continuously performed from 24 hours to three days. Used to monitor the ECG Holter - a small portable recorder that captures clock work heart and writes about his work for the day on the computer. Decrypts these records subsequently cardiologist.
Holter monitoring was named after explorer John Norman. Holter, who first used this device to practice in 1961.
When installing the Holter monitor electrodes are attached to the patient's chest. The electrodes, in turn, connected to a recorder. Of course, the patient is experiencing some discomfort while wearing the device, however, the study itself is very informative and accurate, allowing the cardiologist to determine the exact diagnosis.
The program provides the data analysis and determination of all kinds of disorders of the heart, in particular attacks of angina and arrhythmias, which can significantly increase the effectiveness of the treatment of cardiovascular diseases.
This shows a Holter monitor?
Using Holter ECG prescribed primarily for determining cardiac arrhythmias - atrial fibrillation episodes, premature beats and so on., Which are quite difficult to detect during a short study - normal electrocardiogram.
It happens that some unusual cuts for a healthy heart muscle manifest only during active exercise, strong emotional shock, or in other situations. In these cases, such violations can not be fixed with a conventional electrocardiogram, whereas holter- monitoring of the patient can lead a normal life: to engage in a specific sport, work, take any position of the body, etc.
Also, using the Holter study can identify various circulatory disorders of the heart muscle, in particular ST-segment changes in sport or physical activity.
Can Holter study negatively affect the patient's health?
No harm to health Holter ECG is not. There is also no risk of electric shock.
To avoid damage to the unit while wearing it is not recommended to take a bath or swim, to prevent water from getting inside. It is also not recommended while wearing a Holter pass through a metal detector.
How is the Holter monitor?
Before the device attach to the patient's body, it is recommended to take a shower, because the next day or even more it is impossible to take a bath and take the monitor.
On the chest of the patient and the doctor fixes the electrodes regulates their position. Subsequently, the doctor connects the electrodes with wires recording device which is attached to the patient by means of special belts.
The doctor instructs the patient, teaching him to keep a diary. This is necessary for correct decoding data received from the device. Patient records periods of sleep, wakefulness, physical activity, rest and all the symptoms (pain in the sternum, tachycardia, arrhythmia, etc.) With the exact time.
After installing the devices and a list of instructions the patient can return to his usual rhythm of life and everyday concerns.
Holter monitor - a procedure is absolutely painless. A small inconvenience the patient experiences only while wearing the device when the device leads and a box hidden under clothing. During sleep, it is not recommended to the patient to roll over on his stomach, as the electrodes thus may move that violates the data record.
The results of Holter study
Removes Halter directly cardiologist or nurse. The patient gives the doctor a blog activity and symptoms, which the physician examines the device along with the data.
Depending on the situation, the doctor makes a final diagnosis or send the patient to an additional examination. If one day the results of Holter study did not allow the doctor to make a certain picture, he may appoint a temporary patient wearing a heart rate recording device that the patient will activate itself during the onset of anxiety symptoms.
