Defaecation syncope.
Defaecation syncope is recorded in seven female and two male patients aged between 63 and 78 years seen over a period of nine years. The tendency for defaecation syncope to occur at night contrasts with the rarity of nocturnal defaecation in most old people. The close similarity with micturition syncope is noted.
