S wave

The S wave is a medical term that describes a specific ECG signal that appears on the graph after the R wave and reflects the process of depolarization of the ventricles of the heart.

The S wave is one of the most important ECG indicators and is used to diagnose various heart diseases, such as myocardial infarction, arrhythmias, coronary heart disease and others.

The process of depolarization begins in the myocardium of the ventricles, which are the two chambers of the heart. When an electrical impulse passes through the myocardium, it causes muscle contraction, which causes blood to be ejected from the heart. The R wave reflects the beginning of this process, and the S wave reflects its end.

It is important to note that an S wave does not always appear on an ECG, and its absence may indicate a serious health problem. Therefore, if you notice changes in your health, be sure to consult a doctor for additional research and diagnosis.

S wave - what is it and what is it for? The S wave is one of the components of the ECG signal and plays an important role in assessing the condition of the heart muscle. It represents a high peak of negative voltage that follows the R wave. The wave is formed as a result of the passage of an electrical impulse through the heart muscle (myocardium) from the ventricles of the heart to the atria. This signal reflects the depolarization process that occurs after ventricular contraction.
