The most informative variant of studying the work of the main body of a person is an electrocardiographic study. As a result of ECG on paper, incomprehensible lines are depicted, which contain a lot of useful data on the state of the muscle. In this case, the decoding of the cardiac electrocardiogram is carried out simply - the main thing is to know some features of the entire procedure and the norm of the indicators.
Cardiac electrocardiogram
The ECG records 12 curves, each of which tells about a different part of the heart. To carry out the procedure, electrodes cling to the body. Each sucker is attached to a specific place during the procedure.
Norms for decoding the cardiac electrocardiogram
Each curve consists of a specific set of elements:
- teeth;
- short and long segments;
- intervals consisting of a set of teeth and segments.
Each individual element of the cardiac electrocardiogram shows what exactly happens to one or another part of the organ.
Decoding ECG is carried out in strict sequence:
- The rhythm is determined by the interval between the "R-teeth". In the normal state, they must be equal.
- Experts perfectly know how fast the recording was conducted. These data help to determine the exact frequency of heart contractions. For this purpose, the number of cells between the same "R" teeth is additionally counted. The normal figure is 60-90 beats per minute.
- The duration of each segment and the tooth shows the conductivity of the heart.
- Modern devices for electrocardiograms allow you to simultaneously monitor all indicators, which greatly simplifies the work of specialists.
Deciphering the electrocardiograms of the heart allows you to determine hypotension , tachycardia and many other diseases of the main muscle.
