Fainting Is a Serious Symptom

Jan. 14, 2002 -- Other than a nasty bruise, President Bush is fine after fainting. That's a relief -- because passing out can be a warning that something is very, very wrong.

The President's close encounter with a hard-to-swallow pretzel brought on what is known as a common faint. Doctors call it vasovagal syncope (vay-so-VAY-gall SIN-ko-pee). It happens when the main nerve to the heart gets overstimulated.

WebMD asked Douglas Zipes, MD, president of the American College of Cardiology, to explain what happened. Zipes is director of cardiology and distinguished professor at Indiana University School of Medicine.

"He was chewing a pretzel, and it went down the wrong pipe," Zipes tells WebMD. "He gagged or coughed pretty significantly. When people do that strongly, it can produce a blackout spell."

President Bush is well known for his vigorous physical exercise. Because of this, the nerve to his heart works better than is normal for his age. That's usually a very good thing. But this makes extra stimulation to the nerve -- as might happen during a coughing fit -- more likely to overload the nerve and cause a brief faint. Zipes says it is not unusual for this to happen to an athlete in top condition.

"The president needs a medical evaluation, which I heard he has had," Zipes says. "It is a very simple evaluation," he says, adding that people who have a fainting spell need to see a cardiologist, a heart specialist, for an evaluation. "What happened to the president is a benign episode, but not all fainting spells are benign. One needs to see a trained cardiologist right away."

Lots of things can make a person faint. These include:

If you are with a person who faints, you can help by keeping the person lying flat or sitting forward with his or her head bent below the knees. If heat is a problem, cool the room or move the person to a cooler place.

Fainting isn't a disease -- it's a symptom. It could be a very serious symptom. ALWAYS call a doctor.
