The pacing point wanders within the heart. This is called a wandering rhythm. A wandering rhythm is called a wandering rhythm in the atrium. A wandering rhythm in the sinus node means that the pacing point in the sinus node is not in one part of the heart but is shifted from one part to another. It is often accompanied by sinus arrhythmia. It is a type of sinus arrhythmia. What tests can be done to confirm the diagnosis of atrial wandering rhythm in patients? The following is a brief description: Patients with atrial wandering rhythm may have an electrocardiogram to confirm the diagnosis. The ECG characteristics of atrial wandering rhythm are as follows: 1. 2, P waves in the same lead is slightly different in size and shape, but the direction of the P wave does not change. (This is important, the picture below is not sinus node wandering heart rate). 3, P-P interval mutual difference > 0.12 seconds or more. 4, P-R interval > 0.12 seconds, there can be a slight difference.
