[Paroxysmal supraventricular tachycardia induced by deglutition].

The authors report the case of a 43-year-old man with runs of tachycardia, sometimes atrial and sometimes by reentry, induced by atrial extrasystoles provoked by ewallowing. This rare condition, 21 descriptions of which are referred to, raises the problem of the inducing mechanism, with discussion of the role of mechanical stimulus played by the alimentary bolus or of a reflex of ortho- or parasympathetic origin. The discussion includes a detailed review of this condition and its treatment. The prognosis is always excellent but symptomatic discomfort may be considerable. Spontaneous recovery is possible, as in the case described here.
