EKG. Arrhythmia. What do you mean?

The electrocardiogram shows arrhythmia, usually sinus arrhythmia. In general, the beating of the heart is controlled by electrical activity, which originates from the sinus node of the heart. Therefore, any rhythm originating from the sinus node is called sinus rhythm and belongs to normal rhythm. If the origin of sinus rhythm is unchanged, but the rhythm is irregular, and the difference between P and P intervals on the same lead is greater than 0.12s, it is called sinus arrhythmia. A more common type of sinus arrhythmia is related to the respiratory cycle, called respiratory sinus arrhythmia, which is more common in adolescents and generally has no clinical significance. There are also some rare sinus arrhythmias unrelated to respiration, such as sinus arrhythmia related to ventricular contraction and blood discharge, and wandering arrhythmia in the sinus node. Sinus arrhythmia generally does not require treatment, and patients with primary heart disease are treated symptomatic. If the ECG shows arrhythmia other than arrhythmia, further examination and appropriate treatment measures should be taken.
