Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrocardiogram examination apparatus used for examinations in hospitals and the like.

[0002]

2. Description of the Related Art Electrocardiogram examination is generally performed as a method for examining patients with heart disease in hospitals and the like. This electrocardiogram is a change in the action current according to the cardiac cycle of contraction / relaxation of the myocardium, and an ammeter is attached to the surface of the body, and its temporal variation is depicted using an oscillograph. Arrhythmia, electrical location of heart, hypertrophy / dilation /
It is a powerful test method for diagnosing myocardial disorder, myocardial infarction, coronary insufficiency, electrolyte abnormality, drug effect determination, etc., and is an important test method for determining the course of disease and prognosis. And, as the examination method, a method of laying the patient quietly and attaching a conductor for inducing an electric current to the limbs and the chest is often used.
Standard limb lead the current (I through III) simultaneously Tankyokushi induced Goldberger Goldberger variant of _{(a V R, a V l} , a
V _F ) and monopolar chest lead (V _{1 to} V ₆ ) and a total of 12 leads are generally used for the determination. Specifically, Table 1
It is as follows.

[0003]

[Table 1] Further, an electrocardiogram obtained by applying an exercise load or a drug load to the heart is called a load electrocardiogram, and is performed for the following purpose. A. The ECG is normal at rest, but a circulatory disorder that changes the ECG when a load is applied is found. A. Estimate whether it is a disorder of the heart itself or a disorder of peripheral circulation.

It is important to take a stress electrocardiogram, especially when a patient with an angina-like attack has no abnormality in the resting electrocardiogram. According to Master's results, 37% of patients with angina have normal resting ECGs and abnormalities have been found by stress ECG.

[0007] As the method of this exercise load, there are a master method using a convex staircase, a tremid mill tread-mill method using a moving sidewalk, and an ergometer method for pedaling a bicycle. The general two-step test of a master is to take an electrocardiogram at rest and then move the convex stairs up and down for 1 minute and 30 seconds a number of times determined by your weight and age. . If you climb up and down the stairs and count once, turn right and climb up and down from the other side to count twice. The number of times is determined using a table determined from weight and age, but it is about 18 to 27 meetings. Immediately after going up and down, 2 minutes, 6 minutes, 10 minutes later, and if any changes remain, record the electrocardiogram in the supine position until the changes disappear. The electrocardiogram is now commonly recorded in 12 leads, which is the master's single-to-step-test single two
It is called step test, and the load is doubled and the time is set to 3 minutes. The master double-to-step test.
It's called double two step test.

[0006] In such an electrocardiographic examination, the following points have been pointed out as points to be especially noted for assistance. ECG examination a. Remove as much anxiety and tension as possible from the patient. Explain the purpose and method of the examination in a method suitable for each patient,
Prevent the patient from becoming unnecessarily nervous. Especially for nervous patients, it is desirable that the attending nurse be present. B. Make sure the cortex is clean and not dry at the site where the conductor is attached. We wipe off sweat well in the summer,
Put gauze soaked in saturated saline solution or a special jelly on the conductor to bring it into close contact with the skin, remove the wristwatch, etc., and avoid using electric appliances nearby. In addition, it is necessary to prevent the caregiver from touching the patient during imaging. C. This test should not cause any significant impact or discomfort to the patient. Occasionally, some patients complain of itchiness on the skin with a conductor, so after removing the conductor, wipe it well to remove salt, and since many chest guiding conductors are of the dropper type, this mark is a point. It may become purpura and may remain for a while, so it is advisable to explain this in advance.

[0007] The test results are communicated from the doctor to the patient, but it is necessary to know how they were spoken. At the same time, the nurse should incorporate the ECG results into the nursing plan.

Stress electrocardiographic examination Generally similar to the electrocardiogram described above, but it should be noted that it is sometimes dangerous. As a general rule, stress electrocardiography is not performed when the resting ECG is abnormal or when there is a suspicion of acute myocardial infarction. In particular, caregivers are required to pay attention to the following matters. Check that the patient's condition is the same as when the stress electrocardiogram was instructed. Respiration, pulse rate, body temperature,
If there is a change in blood pressure, report it to your doctor and ask if you should perform an examination. B, because it may cause cardiac arrest in the process of loading,
Be prepared and inspected for cardiopulmonary resuscitation equipment and emergency medicine. C. During the load, carefully observe the patient's condition, and if there is any abnormality,
Discontinue the load and report it to the doctor.In the case of such a patient, it is necessary to perform the load in the presence of a doctor, but especially in the case of a treadmill and a stress test,
It may be applied until just before walking, so it must be done in the presence of a cardiologist. Nowadays,
During the treadmill and stress tests, cardiorespiratory function is being measured simultaneously.

On the other hand, as an inspection instrument used for such an electrocardiographic examination, an electrocardiograph is diversified. This electrocardiograph is one of the earliest developed biometric devices.
One. Electrocardiography is a highly demanding test and can be easily performed by clinical technologists, and it is necessary not only for examination of patients with heart disease but also for pre-, mid-, and post-operative examinations, and monitoring of critically ill patients. There is. The range of electrocardiographs includes, in addition to ordinary electrocardiographs, portable electrocardiographs, vector electrocardiographs, electrocardiogram telemeters, electrocardiogram automatic folding systems, and the like. The main models are 1-element, multi-element (2, 3, 6 elements) AC power supply type, battery power supply type, and related equipments such as vector electrocardiograph, Histo-electrocardiograph, phonocardiograph, There are ultrasonic diagnostic equipment, patient monitoring equipment (polygraph), automatic electrocardiogram diagnostic system, and defibrillator.

The functional characteristics of these models are as follows. The 1-element electrocardiograph is suitable for clinics, laboratories, and facilities with a small number of examinations. It is suitable not only for outpatient examinations but also for outpatient visits because it is easy to carry.In large hospitals, it is necessary to have a multi-element electrocardiograph as a spare for in-hospital visit examinations and emergency tests for inpatients. is there. B. Battery-type 1-element electrocardiograph was recently developed, and a single dry battery 8
It can be used for 300 minutes continuously and 660 minutes intermittently. In order to save power, devices such as hot pens and galva have been devised,
It has a feature as an indication of the future direction of the electrocardiograph. C) The multi-element electrocardiograph is a model that should be prepared for the examination room of a hospital with a large number of examinations because it has excellent processing capacity. D) In a multi-element electrocardiograph, if the number of chest electrodes is too large, problems such as dropping out during the examination may occur, so it is said that a few elements are easy to use. E. The recorder is a direct-writing type on the clinical electrocardiograph and is suitable for reading immediately after recording.
