title: [Syncope in the hyperbaric environment].
abstract: The ever larger number of individuals who practice breath-hold diving suggests an increased need to understand the potential consequences of these sports activities. In this setting, syncope in hyperbaric environment represents a peculiar condition that goes beyond the common classifications of syncope. The pathophysiological mechanisms that underlie its etiology are complex and involve several reflexes that are triggered in these circumstances. Prevention of syncope in apnea divers requires a deep understanding of its pathophysiological mechanisms with inherent preventive measures on behalf of both cardiologists and sports cardiologists.
