There are heart problems that cannot be detected by the electrocardiogram or the echo of the heart. In such cases, you need a test that records the work of the heart precisely around the clock - EKG using the Holter method.
EKG testusing theHoltermethod in the case of:
- disturbance of heart rhythm (palpitations, fast or uneven beating)
- heart block (abnormally slow)
- ischemic heart disease
- fainting and collapsing
- the need to check the operation of an implanted pacemaker
The Holter test apparatus looks like a Walkman. It is attached to the waist belt. It has 5 electrodes that the doctor sticks to the left breast, around the heart. Before that, he degreases it with alcohol or ether. Men have to shave this place.
Wearing the camera must not limit you in anything. On the contrary, for the test to be credible, you should do what you normally do. You just need to keep a diary and write down the times of meals, walks, driving, and describe symptoms (e.g. palpitations, dizziness, shortness of breath). The only exception to the classes is that you cannot take a bath with the holter. Soaking the electrodes would make it impossible to perform the test.
Every now and then you should check that the electrodes are stuck to the skin and connected to the apparatus. If they come off, stick them in the same places with a plaster without a dressing. If the wire comes off the recorder, you must push it in again (the tip acts as a latch).
The great advantage of the Holter test compared to other diagnostic methods is that it shows how the heart is working while you sleep. In some people it is then and only then that its functions are seriously disturbed. When we sleep, most of the body's activities slow down. It happens, however, that breathing is extremely shallow, slow and does not provide the body with adequate oxygen. This has a negative effect on the work of the heart. All these disturbances can be read by the doctor from the recorder.
Electric impulses, constantly produced by the heart, are recorded on a tape or electronically during the examination. After 24 hours, the doctor reads and analyzes the record, comparing it with the notes you keep. He interprets the results using a special computer program. Onon the basis of the prepared graphs, it can make an accurate diagnosis and start treatment.
Some people are wrongly afraid that the recorder will worsen their he alth by disrupting the heart. There is not even the slightest risk. The test does not hurt, it is completely safe and non-invasive, i.e. it does not affect the body tissues.
