What do we know about the diagnosis in cardiology? Many will answer that they are familiar only with the electrocardiogram. This method is really the most popular because it gives the doctor a lot of information about the health of our hearts. But in some situations are required and additional methods of diagnosis, and one sphygmography. This is a completely safe method of research, which does not cause discomfort to the patient. Sphygmography, it’s a recording pulse. To know the results of sphygmography can be very useful because it shows changes in some diseases, such as hypertension or heart defects, etc. The doctor may be interested in “different” pulse, for example sphygmogram the aortic arch, carotid arteries, arteries of the foot, etc.
ECG diagnosis of heart
Pulse, it pushes the blood. At the time of contraction of the heart into the aorta (and the rest of the circulatory system) receives a certain amount of blood (an adult about 50-90 ml). Due to this extra volume of blood pressure in the aorta increases and spreads to other parts of the vascular system. Vessels “taking” pulse wave react to the additional volume of blood periodically expanding and narrowing the lumen. This is possible due to the elasticity of the vessel walls. Heart rate is an important indicator of health and is important not only its frequency but also other characteristics that are fixed on sphygmography.
How do ECG
To register pulse applied ECG. Received pulse curve is called sphygmogram. The patient lies on a couch. It definitely soothe and give time to adapt to the situation because the registration of the pulse is preferably carried out under a calm condition of the patient. To the patient’s body attach special pulse transmitters, which are mounted in the place where you want to catch the pulse. This also depends on the position of the patient. It is very important to the correct location was not strong muscle tension, and therefore particularly care that the patient was comfortable. The study does not take a long time. During sphygmography the patient breathes quietly, may be asked to breathe shallowly.
In sphygmogram there are elements of the curve: preganacies oscillation (a-b-c), bakrota (c-d), plateau (d-e), the decaying limb (e-h), incisura (e-f-g), diabroticina wave g. These elements draws the attention of a doctor.
