R wave

The R wave is a wave that follows the O wave and reflects the process of depolarization of the ventricles of the heart. It is one of the most important waves on the electrocardiogram (ECG) and is used to diagnose various heart diseases such as myocardial infarction, arrhythmia and others.

The R wave is the result of a depolarization process that occurs in the ventricles of the heart. When an electrical impulse passes through the heart, it depolarizes the ventricles, causing them to contract. During this process, the ventricles become more excitable and a tall R wave can be seen on the ECG.

In addition, the R wave can also be used to assess heart rate. If the R wave is too high or too low, it may indicate a heart rhythm problem such as an arrhythmia or heart block.

Overall, the R wave is an important indicator of heart health and can be used to diagnose various cardiovascular diseases. Therefore, if you notice any changes in your heart rhythm, be sure to consult your doctor for an ECG and a more accurate diagnosis.

The R wave (from the Latin Radius - “radius bone”) is one of the standard diagnostic signs on an ECG, symbolizing the restoration of a cardiac muscle cell after its partial or complete contraction under the influence of a cardiac impulse. On the ECG, the R wave reflects the process of restoring the resting potential in ventricular cardiomyocytes. This leads to several distinctive features of the ECG marker - the absence of a wave in the brain leads and the presence of waves in the chest leads. The term “P wave” appeared in Russian literature around the 60s of the 20th century. This name was actively used in medical works by Soviet scientists, and before
