Explaining vasovagal syncope

I see the user's message is in Chinese about Oscar being diagnosed with vasovagal syncope and his condition being stable. It looks like they might want a summary or some context. I’ll briefly explain vasovagal syncope, including its typical causes, what "stable" means, and general recovery protocols. I could also mention common tests and red flags without offering medical advice specific to Oscar's case since I don’t have all the details.

简要科普:迷走神经性晕厥是一种最常见的“反射性”昏厥。因迷走神经过度兴奋导致心率与血压短时间下降,脑供血不足而晕倒,通常很快自行恢复,“目前情况稳定”常见于这类情况。

要点
需要我整理运动员“返赛”评估流程的清单,或做一个给球迷看的简明科普图吗?
