Atrial migratory rhythm

The pacing point moves indefinitely in the heart. This is called a walking rhythm. The pacemaker who moves in the atrium indefinitely is called the rhythm of atrial mobility, and the migratory rhythm in the sinoatrial node means that the pacemaker in the sinoatrial node is not in one part, but is transferred from a certain part to Another part. Often accompanied by sinus arrhythmias. It is a type of sinus arrhythmia. Wandering rhythm means that the location of the pacemaker is not fixed, but it is constantly changing. It can swim back and forth between different parts of the sinoatrial node, or between different parts of the atrioventricular node, or between the sinoatrial node, the atrium and the atrioventricular node. Therefore, clinically, it is often divided into (1) the rhythm of sinus node migration. (2) Rhythm in the atrioventricular node. (3) The rhythm of the sinus node to atrioventricular node junction. Sinus rhythm includes sinus bradycardia, sinus rhythm, sinus arrhythmia, and migratory rhythm in the sinoatrial node. The mechanism of the migratory rhythm in the sinoatrial node may be some inhibitory factors (such as increased vagal nerve tension or drug effects), which inhibits the faster-frequency parts of the sinoatrial node, and the slower-frequency parts start to work . When these inhibitory factors were removed, the faster-paced pacing site resumed its pacing function, and the slower-frequency site was suppressed again. This cycle continues, making the sinus rhythm faster and slower, and the P wave morphology also changes, forming a sinus rhythm in the sinoatrial node. This rhythm is usually seen in healthy people, but it is also common in patients with digitalis poisoning.
