Is vasovagal syncope hereditary

summary

Recently, I always feel dizzy. I often feel dizzy when I walk. I have fainted on the ground several times. I can't pay attention at ordinary times. I'm very worried about what I'm suffering from, so I went for an examination. The doctor said it was vasovagal syncope. Now let's talk about whether vasovagal syncope can be inherited.

Is vasovagal syncope hereditary

First, vasovagal syncope is very common. It often recurres, especially when the mood is under considerable pressure, extreme fatigue, pain, panic, or in a crowded or sultry room. Besides the heart, the blood vessels in other parts of the body are not innervated by the vagus nerve.

Second: syncope can be caused by cardiovascular diseases, nervous system diseases and metabolic diseases, but many patients can not find the cause according to the clinical history, physical examination and auxiliary examination, which has been called "unexplained syncope" for a long time.

Third, neuroendocrine regulation is also involved in the pathogenesis of vasovagal syncope, including renin angiotensin aldosterone system, catecholamine, 5-hydroxytryptamine, endorphin and nitric oxide, but the exact mechanism is not clear.

matters needing attention

Although vasovagal syncope itself is not fatal, but the harm of sudden syncope can not be underestimated, many patients have serious trauma, leaving permanent damage, or even loss of life, so we must pay attention to it.
