defibrillation |
Also found in: Dictionary/thesaurus, Medical, Encyclopedia, Wikipedia | 0.03 sec. |
defibrillationUse of electrical stimulation to restore a chaotic heartbeat to a rhythmical pattern. In fibrillation, which may occur in most kinds of heart disease, the heart muscle contracts irregularly; the heart is no longer working as an efficient pump. Paddles are applied to the chest wall, and one or more electric shocks are delivered to normalize the beat. In patients suffering with arrhythmia, implantable defibrillators are inserted into the chest with leads threading through veins into the right side of the heart. The first was implanted in 1980 and by 1999 around 400,000 had been implanted worldwide. How to thank TFD for its existence?

| Imagine yourself confronted with someone who needs to be intubated, who needs an IV line, who needs to be defibrillated all at once and get on the radio, alert the hospital, get orders, and all this at the same time controlling a crowd, perhaps. Studies show that if victims are defibrillated within a minute or two after arrest, more than 70 percent survive. Last month, a 70-year-old passenger aboard another Chicago-bound plane was successfully defibrillated by an American flight attendant while the plane was waiting to take off from North Carolina's Raleigh-Durham airport. |
