In medicine, teeth are important for diagnosing various heart diseases. Waves are electrocardiographic waves that are recorded on an electrocardiogram (ECG) and allow you to evaluate the electrical activity of the heart.

The waves can be positive or negative, and their shape and amplitude can vary depending on various factors such as age, gender, physical activity and others. The teeth can help the doctor determine the presence of arrhythmia, myocardial infarction, angina pectoris and other diseases.

To obtain accurate information about the patient's health status, it is necessary to conduct an ECG, which involves recording waves on paper or film. ECG results can be interpreted by a doctor, who can make a diagnosis and prescribe appropriate treatment.

Thus, the waves play an important role in the diagnosis and treatment of heart disease, and therefore it is necessary to know their meaning and be able to interpret ECG results.

The waves are electrical impulses reflected from the heart muscles, in the form of sharp peaks located on either side of the heart rhythm line. When receiving an ECG in a dental office, several thousand heartbeat cycles are recorded within a few seconds, which allows you to get a complete picture of their rhythm and disorders. The presence and appearance of the teeth makes it possible to detect heart rhythm abnormalities, such as tachycardia, extrasystole or conduction blockades. This is important for obtaining a complete picture of changes in heart rhythm during examination of the patient, and also allows us to determine the results of treatment aimed at normalizing the frequency and depth of heart contractions.

It is believed that ECG waves reflect the process of formation of the electrical activity of the heart; this occurs as a result of several electrical processes that are developed and implemented in the heart. Thus, during the development of waves, the first stage of the electrogram is the effect of systolic excitation of the heart. To this stage, wave A is transmitted from the sinus node, arriving and additionally activating the interventricular septum and the anterior muscles of the ventricles. It is during the action of wave A that the heart rate increases and the pressure in the ventricular cavity increases at the moment of blood ejection from the heart. After this, a two-phase process of contraction and relaxation of the ventricles occurs, ending with the appearance first of the S–T interval, then of the negative T–P segment. All three prongs are basic for deciphering the examination results. The R, T and S waves are recorded depending on the location of excitation in the myocardium and reflect changes in blood volume in the interventricular septum in certain areas. Thus, the R and S waves arise near the apex of the heart in its anterior fibers and change their appearance according to the position of the electrical axis of the heart, which deviates to the left or to the right. While the T wave is almost always positive, it is always located at the top of the R wave.
