Accepted Answer

Concussion: Generally should resolve within a week headaches can persist.

Question 2

can constipation cause a vagal response (i.e. orthostatic bp)?

Accepted Answer

Syncope: Bearing down causing algal nerve stimulation and resulting low BP and hr. Hypotension and bradycardia can cause symptoms from dizziness to fainting or syncope.

Question 3

are you born with vagal response or viovagle synscope?  and why would it just start happening? are there warning signs? is it caused by stress/anxiety

Accepted Answer

Vagal responses: Activation of the vagus nerve typically leads to a reduction in heart rate, blood pressure, or both. This occurs commonly in the setting of gastrointestinal illness such as viral gastroenteritis or acute cholecystitis, or in response to other stimuli, including carotid sinus massage, Valsalva maneuver or pain from any cause, in particular, having blood drawn. The extreme manifestation is syncope

Question 4

have had 2 rf ablasions for svt. not "successful." possible vagal response to chronic reflux? triggered by rf stretta  for gerd?

Accepted Answer

Doubt it: Consider a different specialist for a second opinion on svt.

Question 5

can the vagal nerve or vagal response be overactive or malfunction? because whenever i eat anything i get very lightheaded, faintness, pale and shaky.

Accepted Answer

Vagal Nerve Problems: Yes, an exaggerate vagal nerve response can contribute to dizziness. Probably, this happens when the vagal nerve causes the heart rate to slow down.

If this happens any more often than rarely, go see your doctor. You need to exclude irregular heart rate rate, fluctuation in blood pressure, and sudden rising or falling  blood sugar - three reasons for dizziness around meals.

Question 6

if a md presses on the eyes to induce vagal response, can it cause damage in a person with ocular hypertension?

Accepted Answer

Not in vogue : As far as I know, the practice of digitally stimulating the eyeballs forcefully to produce an oculocardiac reflex is rarely if ever utilized. This practice is also not ever advisable in persons affected with glaucoma or ocular hypertension. The fact that this reflex can occur in adults, eliciting bradycardia, junctional rhythm and asystole, all of which may be life-threatening, is not advisable.

Question 7

can a er doctor pressing on my eyes to produce a vagal response to slow down hr, cause damage to someone with ocular hypertension

Accepted Answer

Unlikely: The brief interval during such pressure might slow or stop the circulation for several seconds but it will not do  any harm unless prolonged.

Question 8

dobutamine stress result dose till 40ug/kg/min archived 75% of target hr has palpitations only during infusion no chest pain,mild heaviness left shoulder high dose dob mild basal inferior wall hypokinesia normal response 63% resting to 75%within test?

Accepted Answer

: The dobutamine stress test is positive. You likely need a coronary angiogram.

Question 9

is heart rate elevated during a vagal resonse to blood draw?

Accepted Answer

NO!: The essential pathophysiology of a vagal reaction is slowing of the heart. If the heart rate has increased, it is not a vagal reaction.

Question 10

how common is it for your pulse rate to go high during a vasovagal response?

Accepted Answer

Vasovagal: Pulse rate drops during the event and rises in recovery phase.
