We describe three athletes who had syncope after (case 1) or during (cases 2, 3) hyperventilation. During the episode, ECG showed prolonged sinus arrest. Clinical data and noninvasive investigations were normal and the phenomenon was not reproducible. Electrophysiological study after autonomic blockade allowed a prolonged intrinsic heart rate in case 1, and abnormal corrected sinus node recovery time in cases 1 and 2. During follow-up, symptomatic sinus arrest provoked by deep inspiration occurred in case 3. These cases document prolonged asystole of unknown etiology, secondary to hyperventilation, and probably caused by different vagally-mediated mechanisms.
我们描述了三名运动员，其中一名（病例1）在过度换气后出现晕厥，另外两名（病例2和3）在过度换气期间出现晕厥。发作期间，心电图显示窦性停搏延长。临床资料和无创检查均正常，且该现象无法重现。自主神经阻滞后的电生理研究显示，病例1的固有心率延长，病例1和2的校正窦房结恢复时间异常。在随访期间，病例3因深吸气诱发了有症状的窦性停搏。这些病例证明了继发于过度换气的不明病因的长时间心脏停搏，可能是由不同的迷走神经介导机制引起的。
