摘要
本文在350m氦氧模拟饱和潜水的22天过程中,对4名男潜水员进行中午及夜晚睡眠时连续心电图监察。发现普遍有不同程度的心率减慢和心电不稳,表现为高电压、电交替、早期复极和异位搏动增多。其中1例原有显著心动过缓者,除以上变化更大外,还曾先后3次发生持续数小时的缺血型ST-T改变。作者认为,上述各种变化可能主要与高气压条件下副交感神经活动的增强有关。因而提出凡心率过慢者,应避免进入高气压环境。
Continuous ECG monitoring was carried out in 4 male divers during afternoon naps and night sleeps in a 22-day simulated 350m He-O<sub>2</sub> saturation dive experiment. In all the divers varying degrees of heart rote decrease and electric instability were found,exhibited as high voltage, QRS-T electric altemans, early repolarization and frequent ventricular ectopic beats. In one diver with pronounced bradycardia, the above-mentioned changes were found even greater, and besides, very prominent ischemic ST-T changes lasting for hours occurred successively for 3 times. It was considered that all these changes may be related mainly to the enhancement of parasympathetic nervous activity under the specific hyperbaric condition.
