Te presence of a reflex mechamsm m man which triggers a bradycardia during apnea has gained rather wide acceptance in the literature. In resting man, there has been observed a heightened bradycardia with apneic face immersion in water. Past investigators have observed both a &dquo;breath holding&dquo; and a &dquo;water immersion&dquo; or &dquo;diving&dquo; reflex in the resting man. However, there is disagreement in the studies which have investigated the presence of these reflexes in exercising man. Several investigators observed bradycardia during apneic dmes.
