It is a type of Vasovagal response.

This type of needle phobia is uniquely characterized by a two phase vasovagal response.

So I think we can safely conclude you fainted, the consequence of a vasovagal response due to holding your breath."

If the vasovagal response is stimulated by the pressure of impaction, the patient may become dizzy and hypotensive.

Episodes of vasovagal response are typically recurrent, and usually occur when the predisposed person is exposed to a specific trigger.

Medication therapy could possibly prevent future vasovagal responses; however, for some individuals medication is ineffective and they will continue to have fainting episodes.

The three most frequent adverse events were bruising at the puncture site, temporary worsening of the original symptoms intended to be treated, and vasovagal response.

Vasovagal response (fainting)

Major complications are pneumothorax (3-30%), hemopneumothorax, hemorrhage, hypotension (low blood pressure due to a vasovagal response) and reexpansion pulmonary edema.

A vasovagal episode or vasovagal response or vasovagal attack (also called neurocardiogenic syncope) is a malaise mediated by the vagus nerve.

In the cases of blood-injection-injury phobias a two-phase vasovagal response is observed: first a brief acceleration of heart rate, then its deceleration, bradycardia, and dropped blood pressure.

The protocol was to keep her like this for an hour; if she didn't pass out, I was supposed to inject her with an adrenaline-like drug to stimulate the vasovagal response.

In response to this, graded exposure approaches can include a coping component relying on applied tension as a way to prevent complications associated with the vasovagal response to specific blood, injury, injection type stimulus.

The doctor said that one possible diagnosis may be a benign fainting condition known as neurocardiogenic syncope.

He told me I had neurocardiogenic syncope, which meant I could black out without warning.

It told Lewis that he had a normal athlete's heart and a benign fainting condition known as neurocardiogenic syncope, or vasovagal fainting.

The Brigham and Women's team disputed the findings at Baptist hospital and concluded that Lewis had a benign neurological condition, known as neurocardiogenic syncope.

A vasovagal episode or vasovagal response or vasovagal attack (also called neurocardiogenic syncope) is a malaise mediated by the vagus nerve.

The abnormality is known variously as neurally mediated hypotension, vasovagal syncope (fainting), vasodepressor syncope and neurocardiogenic syncope.

POTS is often accompanied by vasovagal syncope, also called "neurally mediated hypotension" (NMH) or "neurocardiogenic syncope" (NCS).

Mudge said that Lewis had a benign fainting condition known as neurocardiogenic syncope, and that he was "quite optimistic that under medical supervision, Reggie Lewis will be able to return to professional basketball without limitation."

It was determined after testing by doctors that the cause of his collapse was neurocardiogenic syncope, a type of fainting spell, and that he received a concussion and lost consciousness after his head hit the ice.

A second, equally distinguished team, at Brigham and Women's Hospital, disputed the first team's findings, saying that Mr. Lewis had a normal athlete's heart and a nonfatal condition called neurocardiogenic syncope, or vasovagal fainting.

Strives to heighten awareness of dysautonomia conditions (postural orthostatic tachycardia syndrome, neurally mediated hypotension, neurocardiogenic syncope, vasovagal syncope, generalized dysautonomia, birth dysautonomia, non-familial dysautonomia, post-viral dysautonomia) within the pediatric and adolescent medical communities.

After a week of further tests, Dr. Gilbert Mudge gave a second opinion, that Lewis did not have a life-threarening heart ailment but merely suffered from a comparatively benign neural condition, neurocardiogenic syncope, in which confusing signals regulate the speed of the heart beat.
