Pediatric arrhythmia
The development of arrhythmias is closely related to abnormalities in the cardiac conduction system. Normal cardiac arousal originates from the sinoatrial node. Arrhythmia (arrhythmia) can be formed if the heart conducts contraction and relaxation by spreading through the heart's conduction system at a certain frequency, sequence and speed, which is called normal sinus rhythm. ).
