Heart ultrasound: how research is conducted?
Heart ultrasound — a procedure that assigned patients in many cases. If you have any suspicion that the cause of disease — violation of blood circulation, the study can give a comprehensive result.
But is it safe ultrasound? And how it differs from ECG? Characteristics of the study, interpretation and contraindications have to know anyone who is interested in their own health.
What is the research?
The principle of any of the ultrasound diagnosis: with the help of safe radiation determine the health status of the organ being examined. Ultrasound is reflected from tissues and sends information to the computer, where with the help of special software on the simulated patient. Feature ultrasound of the heart that the doctors have the opportunity to evaluate his work in real time and with a probability of 90 % at the first examination to find the disease. Normal values differ depending on age and lifestyle, there are also individual marginal results for pregnant women and patients with chronic diseases. On the condition of the heart is influenced by many factors, so the diagnosis is made not only on the basis of this study.
Ultrasound of the heart will give exhaustive information about all the functions of the authority, the peculiarities of its structure, allows you to see the results of his work (movement of blood), to assess the condition of the vessel. The method is painless, harmless and accurate, requiring no training, so today is one of the most popular.
Often after any complaint to the cardiologist, the doctor sends the patient for an ultrasound, which shows the features of the functioning of the authority and the existing deviations from the norm. This symptom can be not only a pain in the heart region, but also other changes that indicate the progression of the disease:
- noises during auscultation (listening with a stethoscope);
- swelling of extremities;
- constant headache;
- any chest pain;
- shortness of breath;
- serious lung diseases.
Ultrasound of the heart and is prescribed for pregnant: during this period, the load on all organs increased, so it is important to monitor the status of women and the fetus. Preparation for childbirth should include and examination of the organs of blood supply.
To monitor the condition of heart necessary, and those who have experienced a heart attack, recovering from cancer and has problems with pressure differences. It is also desirable to evaluate the heart muscle for those who are professionally engaged in sport or regularly perform physical exercise — this activity affects the blood flow.
At the heart ultrasound can determine:
- features of the anatomical structure of the body;
- heart attack and stroke;
- the presence of tumors in the heart;
- problems in the operation of the valves;
- increase or decrease of the body;
- the presence of heart disease;
The study shows a lot. During the procedure, the estimated thickness of the myocardium, the condition of the valves of the heart cavities.
At the end of the procedure, the technician who conducted the ultrasound of the heart, fills in a special form according to the study, which is communicated to the attending physician to determine diagnosis and treatment. Form about 18-20 points. Then will indicate the volume of the cavity, the speed of blood flow and the General data about the body. The rate will vary depending on age, presence of chronic diseases, and many other factors.
For a healthy adult who leads a balanced lifestyle, boundary indicators, consider:
- the diameter of the aorta is 2 to 3.8 cm;
- the trunk of the pulmonary artery — to 3.1, and the mouth is 1.7–2.4 cm;
- the volumes of the right and left ventricle at the end diastole — 1-2,6 and 3.5–5.8 cm, respectively.
Depending on the results determined by the deviation from the norm, revealed the cause of this difference. In addition to the standard indicators, to determine the presence of fluid in the pericardium, the back flow of blood and signs of increased valve: in norm they should not be.
Decoding is engaged in the doctor, the specialist who conducts the study, explanations are not included. The patient may ask the physician a transcript of the indicators and their compliance with the norm. As practice shows, often the attending cardiologist will carry out the procedure.
How is the procedure?
Those who first encounters with ultrasonic examination of organs, important to know:
The myth about the harmfulness of radiation has long refuted, and carry out the procedure can everything and many times. Before you go for it, ask the doctor how to do ultrasound of the heart, generally, and specifically to you: one-dimensional, two-dimensional, using the contrast (infusion into the blood special substances) or under stress.
Conventional ultrasound is carried out so:
- the patient is at rest (no physical exertion before the procedure) strips to the waist;
- he lies down on the couch and relaxes;
- training — chest smeared with a special composition in order for the machine to slide freely on the surface of the skin (depends on the accuracy of the result);
- within an hour the technician carrying out the ultrasound machine leads to the heart.
The main condition — that the patient was not nervous and was in a state of rest.
The principle of ECG
ECG (electrocardiography) is a procedure that is usually administered along with ultrasound. This comprehensive survey provides an opportunity to assess almost all aspects of the work of the heart and to obtain the most accurate results. However, the methods can be used separately from each other.
The ECG records fluctuations of the heart and displays them in graph form — cardiogram. These data are needed for determination of arrhythmia, additional strokes and many other problems associated with heart activity.
The procedure runs for several minutes: the patient’s skin capture special sensors in the chest area, which transmit the data to the computer. Requires no preparation, no contraindications to the procedure no.
Choosing between ultrasound and EKG, need to understand that they show different aspects of the work of the heart. Therefore, doctors recommend to carry out both procedures at the time of examination. To return to repeat the study as often as needed harm they bring.
The interpretation of results depends on age, gender and lifestyle of the person. ECG checks the data of the doctor. After a comprehensive survey, he determines the reliability of the research, specific diagnosis and prescribes treatment. In the future held ultrasound the patient will have a lot of time and after the end of the disease: this is his preparation to recovery.
Despite the relative accuracy, or ultrasound or electrocardiography does not give an answer to the doctors for some issues. None of the methods do not determine the General condition of the coronary arteries. Separately, ultrasound of the heart will not indicate causes of cardiac arrhythmia and ECG — structural features of the body.
What affects the results?
Despite the fact that there is no need of preparation for the procedures, sometimes the results of the study may be inaccurate.
The results of ultrasonography and electrocardiography depends on the following:
- physical activity of the patient per day;
- experience who conducts the procedure;
- the state of the art;
- the anatomical features of the patient.
Despite the fact that around ultrasound of the heart all the time, the debate and the rest of the myths, this procedure is absolutely safe for adults, children and pregnant women. Besides, ultrasound is fast and informative.
