Methods for investigation of cardiovascular system

Functional methods of research of the cardiovascular system are widely used in the diagnosis of heart disease.
Electrocardiography (see) is of great importance in the diagnosis of myocardial infarction, in determining its location and extent, in dynamic observation of it. It helps you diagnose arrhythmias, heart disease, lesions of the myocardium, pericardium and other Addition to electrocardiographic method in the study of electrical processes taking place in the heart, is vectorcardiography (see). Essentially supplements auscultation of heart phonocardiography (see Ponografia), because with its help identify different tone changes, qualify the nature of the noise of the heart, and those that are poorly captured on auscultation. When tachycardia, arrhythmia application of phonocardiography allows you to specify, in what phase of the heart activity (systolic or diastolic) noises appear that it is important for the diagnosis of one or another of heart disease.
For the study of myocardial contractile function of the applied and a number of other instrumental methods of the heart: ballistocardiography (see), cardiography (record apical or cardiac impulse), kinetoterapia (record of breast fluctuation, connected with the activity of the heart) and other Electrotomography enables you to separately study the reduction of the different parts of the heart, which helps in the diagnosis of heart disease, aneurysm of heart and so on, To assess the state of the cardiovascular system and apply such methods as stegnography (see), phlebotomine (see), rheography (see) and other
In the diagnosis of heart defects is of great importance pressure measurement in the cavities of the heart and large vessels. Simultaneously with the pressure measurement in the cavities of the heart can take their blood for determination of oxygen and carbon dioxide , and type in the heart cavity special paint to determine its circulation in the blood. On paint circulation control many parameters of a condition of blood circulation: systolic and minute blood volume, weight of circulating blood, blood flow velocity, etc. Instead of paint in the cavity of the heart, you can enter a radiopaque substance (see Angiography) and make series of pictures, which judge about changes cavities of the heart, the direction of blood flow, and so on, the circulation is also studied using radioisotopes.
