ニュース速報+板のほうがいいかも知れないけど、食べてて意識を失うっていうのは脳卒中みたいなものなんでしょうか。父ブッシュも日本訪問のとき風邪で倒れたことがあるけれども。
専門家のご説明を希望します。

米大統領がテレビ観賞中に意識失う、その後の検査で健康に問題なし
［ワシントン １３日 ロイター］ ブッシュ米大統領が１３日夜、大統領官邸でプレッシェルを食べながらテレビでフットボールの試合を観戦中に意識を失い、寝椅子から落ちる事態が発生したが、その後の検査で健康状態に問題はないことが分かった。
担当医であるリチャード・タブ空軍大佐が明らかにした。
同大佐によると、大統領はここ数日、気分の不調を訴えていた。
不調に加えて、食べかけのプレッシェルを上手く飲み込めなかったことが重なり心拍数が低下、気絶する結果となった。
同大佐によると、大統領は意識を失って頭を床に打ち、左側のほお骨に擦り傷、また下唇に小さな傷を負った。
ただ、大統領が意識を失ったのはほんの数秒間だった、という。（ロイター）

意識消失の原因は非常に多岐にわたります。
脳疾患、たとえば血管障害やてんかんのみに限らず、様々な原因での心拍出量の低下、
低血糖発作、血液のイオンやその他の成分の変化、精神症状・・・など数え切れない
くらいあります。
さて、大統領のケースの場合、ものを食べているときに心拍数が低下しほんの数秒間
意識消失を起こしたというのは、推測に過ぎませんが、迷走神経反射性失神を疑いま
す。排尿排便後や食後に急に心拍数が低下し血圧が低下し生じるものです。脳卒中に
関しては否定的です。意識消失の時間が短すぎます。

そのニュースは聞きましたが、要職にある人の体調については
正しく報道されるとは限らないのでわかりかねます。
NY Timesも同じ内容でした(AP配信)
The White House physician, Dr. Richard Tubb, examined Mr. Bush and "did
not find any reason to think it was serious," Mr. Fleischer said. According to
Dr. Tubb's explanation, the president's fainting was caused by "a temporary
decreased heart rate brought on by eating a pretzel that did not go down
right," Mr. Fleischer said.
Mr. Fleischer said the pretzel had evidently stimulated the vagal nerve, which
can decrease the heart rate and cause fainting.
The president believed he was unconscious only briefly because when he
awakened his dogs were in the same spot, Mr. Fleischer said. "He said the
only difference is that they were looking at him funny," Mr. Fleischer said.

WASHINGTON (AP) -- President Bush fainted briefly after choking down a pretzel while
watching a football game, a type of spell doctors say they see often but isnothing to worry
about.
White House physician Dr. Richard Tubb said Bush quickly recovered from the episode Sunday,
apparently brought on by a temporary decrease in heart rate while coughing.
The president fainted while alone in a room at the White House residence, watching the
Baltimore-Miami National Football League playoff game on television and eating pretzels.
Tubb said Bush believes he was out only for a few seconds because when he awoke, his two
dogs were sitting in the same position they were when he lost consciousness.
``But the dogs were looking at him funny,'' White House spokesman Ari Fleischer added.
The pretzel-caused coughing apparently stimulated a nerve that further slowed Bush's heart
rate, Tubb said.
In medical terms, it's called vasovagal syncope. The body sends a signal to the heart via the
vagus nerve, slowing heart rate enough that the person briefly loses consciousness.
It's very common. Fear, even intestinal cramps, can cause vasovagal fainting.
``It's thought that pretty much everybody has one simple faint in their life. We see folks every
day that have had a vasovagal reaction,'' said Dr. David Skibbie of Inova Fairfax Hospital in
suburban Virginia. ``It's alarming, but if everything checks out it's fine and they can go home
without any concerns about their future health.''
A vasovagal episode isn't the only possibility, Skibbie said. Somewhat less common is cough
syncope, where a coughing episode -- similar to what Bush reportedly had -- can increase
pressure in the chest enough to momentarily lower blood pressure. It, too, is benign.
