1940C. J. Wiggers in Amer. Heart Jrnl. XX. 419 Defibrillation can be accomplished in the dog by the..application of several comparatively weak shocks. 1956Blakiston's New Gould Med. Dict. (ed. 2) 321/1 Defibrillator. 1958Electronic Engin. XXX. 24 The complete circuit of the defibrillator is shown. 1961Lancet 5 Aug. 293/2 Heart action is restored within a few minutes of releasing the aortic clamp. This results in perfusion of the coronaries with comparatively warm blood, and although ventricular fibrillation seems to be invariable at this stage it reverts easily with a defibrillating shock. 1967Spectator 11 Aug. 159/3 Ventricular fibrillation may be controlled by a piece of electrical apparatus known as a defibrillator. |
