Abstract:
The P wave of electrocardiogram is the atrial depolarization wave, which represents the atrial excitement.P waves are associated with many diseases, which can be used as diagnostic standard and prognostic index, and may have significant clinical value.Neurally-mediated syncope(NMS)is primarily mediated by autonomic abnormalities or autonomic dysfunction.NMS is also the most common type of syncope in children and adolescents.Many studies have shown that P waves can provide a lot of information related to NMS.In patients with NMS, P wave duration, P wave dispersion and P wave amplitude are statistically significant.Therefore, P wave of electrocardiogram may become an important ECG indicator for the prognosis of NMS in children and adolescents.Here we review the relationship between P wave of electrocardiogram and prognosis of NMS in children and adolescents.
