Advice 1: How to read an EKG

Among the instrumental methods of examination that perfection must possess a medical practitioner occupies a leading position electrocardiogram. This simple, inexpensive and essential method allows to diagnose such a serious catastrophe in the human body, as arrhythmia and myocardial infarction. The method is based on the study of bioelectric activity of the heart. ECG consists of several teeth, segments and intervals, which reflects the process of propagation of the excitation wave in the heart.
How to read an EKG
Instruction
1
Check the correctness of the logging technique. When recording an ECG should not be interference and current guidance. The value of the control millivolt should be 10mm.
2
Analyze the heart rhythm for regularity and heart rate, identify the source of excitation and conduction. The regularity of heartbeats to determine the relative duration of intervals R-R. If the right rhythm heart rate calculated by dividing 60 by the R-R interval expressed in seconds.
3
Determine the electrical axis of the heart by calculating the algebraic sum of the amplitudes of the teeth of the QRS complexes in any two leads from the extremities, such as I and III standard leads.

4
Consider and analyze the atrial tine P. Measure the amplitude of the prong of the contour to the top of the tooth, it should not exceed 25 mm. Determine the length of the prong from its beginning to the end, in a healthy person, it is 0.1 s.
5
Measure the interval PQ, showing the rate of momentum transfer from predserdii to the ventricles. It should be in the interval from 0.12 to 0.1 seconds. Analyze the ventricular QRS complex by measuring the amplitude and the duration of each prong in the complex. The width of the entire stomach complex should not exceed 0.1 S.
6
In the analysis of the T wave reflects the phase of refractoriness or relaxation of the heart muscle, determine the polarity (direction), evaluate and measure the amplitude. Normally, this tooth needs to be positive, to have the same direction as the main prong of the ventricular complex to have sloping rising and a few more cool downward the knee.

Advice 2: How to read an EKG

An electrocardiogram is an effective and generally accepted medical procedure to accurately diagnose heart disease and determine the health of the cardiovascular system. Few people are able to first correctly decoding cardiogram therefore, decryption requires special knowledge.

1
The final interpretation of the ECG depends on what parts of the body were attached to the electrodes, and the process of interpretation is called abstraction. There are three types of abstraction is the connection between the left and right hands, the connection between left foot and right hand and also the connection between left foot and left hand. All three leads there is a normal arrangement of teeth for a healthy person – the value of teeth of the second diversion must be equal to the sum of teeth of the third and right leads.
2
Measure the magnitude or amplitude of teeth and the amount of space between them for the analysis of the cardiogram. Learn the letter symbols for the teeth. Prong R is called atrial and shows the work of the Atria, while the Q-wave shows the activity of the upper lobes of the heart. The R-wave indicates the activity of the lower part of the heart.
3
The PQ interval shows the effect of both Atria, and the action of the ventricles is determined by the QRS interval. The activity of both ventricles appears the ST segment – T wave indicates the normal state of the heart muscle cells.
4
Measure the gap between the teeth P and Q – it should not be less than 0.12 and more than 0.1 seconds. Deviation from this norm is the indicator of an unhealthy heart. The teeth of the QRS should be held in the interval of 0.06-0.1 seconds.
5
With ECG, you will be able to calculate the electrical axis of the heart and see the heart rate, which shall not exceed eighty beats per minute in a healthy person. The minimum value of the norm heart rate sixty. ECG allows to identify violations of the heart muscle and to take medical measures for treatment of the patient.

Advice 3: As a cardiogram

Electrocardiogram (ECG) is a recording of electrical potentials of the heart, by which to judge his work. ECG is removed in a special room with the help of the electrocardiograph. The study is carried out after 10-15 minutes of rest and no less than 2 hours after a meal.
As a cardiogram
You will need
  • - disposable sheet;
  • - 70% alcohol;
  • Vata;
  • - conductive gel.
Instruction
1
Ask the patient to undress to the waist and free from wear wrist and leg.
2
Cover disposable couch sheets. Ask the patient to lie on your back and relax muscles.
3
Moisten a cotton ball with 70% alcohol solution and wipe internal surfaces of the wrists and shins. Then apply to the same place the gel Explorer or just moisten the skin with physiological saline solution. Unravel the wires of the electrodes for the limbs. They look like big pegs or feelers. Place electrodes on the wrists and calf so that the metal plates on their inner surfaces were leather, wetted guide. On the right wrist is superimposed a red electrode on the left is in yellow. On the left calf of green electrode on the right is black.
4
Apply rubbing alcohol to the skin of the breast. Take the electrodes for the chest leads. They are metal hemisphere with rubber suction cups and wires of different colors. Select the electrode with the red wire, it needs to be labeled V1. Find the right edge of the sternum 4 the edge. Place the electrode V1 and the edge, moisten the skin with conductive gel. In order to keep the electrode stuck to the skin, squeeze the pear-suction Cup, attach the electrode to the skin and release the bag.
5
Electrode V2 that have the yellow wire put just under 4 edge, but the left edge of the sternum.
6
Feel the patient's left collarbone. Mentally divide it in half. The line running down through the middle of the clavicle, find 5 rib. Take the V4 electrode with a brown wire and attach it to the skin under the felt 5 rib.
7
The electrode V3 (it has a green wire) position between V2 and V4.
8
Press left hand of the patient to the torso. On a line corresponding the place of pressing the hands to the body again, look 5 rib. To the skin under the 5 rib attach the electrode with the black wire (marked with V5.
9
Remove the left hand of the patient from the body. On the same level as V5, but 1-2 cm closer to the couch put the last electrode V6, with blue or purple wire.
10
Turn on the ECG device. Check the speed of paper: 50 mm×s-1 or 25 mm×s-1. Ask the patient not to move during the study.
11
Click on the "start" button. After finishing ECG record tear off the paper tape, record on it the surname, name, patronymic of patient, age and date of study.
12
Remove the electrodes from the skin. Unplug the apparatus.

Advice 4: That shows the electrocardiogram of the heart

Cardiogram of the heart it reflects the electrical activity, which can be judged on such parameters as the rhythm and strength of cardiac contractions, blood flow to the heart muscle. ECG is essential in the diagnosis of most cardiovascular diseases — hypertension, ischemic disease of heart, myocarditis, arrhythmias.
That shows the electrocardiogram of the heart
This study does not bring the patient any discomfort, pain or harm. The person is comfortable is on the couch, his limbs and chest to attach the electrodes. The wires from them join in the apparatus, from which the paper tape with the cardiogram. During the attack of arrhythmia or heart pain exactly the electrocardiogram will show how dangerous the violation occurred. Up-to-date research — the key to proper treatment depends on the patient's life. This study most accurately measures your heart rate, that is, the electrical activity of the heart. If the heart beats ritmichno, cardiography accurately and in detail will show what's going on. The doctor will be able to determine the source of pathological electrical signals, to see the path, to assess the degree of seriousness and the effectiveness of treatment of arrhythmia. ECG also gives the opportunity to detect the beat - contraction of the myocardium. In addition, the study can identify violations such as atrial flutter and flicker. Less accurate measurement of the electrocardiogram is condition of the heart muscle. Decoding cardiogram, any cardiologist will be able to notice the patient's likelihood of a heart attack. But in the future, these deviations should be confirmed by other studies. More informative ECG, who acted in a moment of intense physical activity of the patient. Checking of electrical signals passing through the heart - quick, affordable and often very useful method of diagnosis, but it is still indirect examination. Sometimes the electrical signals pass through the seriously damaged areas with virtually no latency, giving the normal curve. ECG is unable to identify coronary atherosclerosis. Decoding cardiogram performed by a physician with consideration of complex clinical data of complaints of the patient, knowledge of the history of the disease, assess its condition, the data of the medical examination.
