对24例拉萨地区的窦性心动过缓患者进行了观察,入院时平均心率为47.4±5.8次/分,心电图均示心肌缺血,动脉血氧分压16例为3.86±0.84kPa,动脉血氧饱和度为49.5±13.3％。经供氧与“冠参片”治疗或高压氧舱等治疗后,22例痊愈;另2例返回平原1周后自然痊愈,心电图示心肌缺血消失,心率。动脉血氧分压与氧饱和度等明显提高,与治疗前比较,差异均有非常显著意义(P<0.01)。作者认为:这是高原低氧所引起的一种特发性疾病,是一种新型的高原病,暂命名为“高原窦房结功能低下症”。
The 24 patients with sinus bradycardia in Lhasa were observed. The average heart rate at admission was 47.4 ± 5.8 beats / min. The electrocardiogram showed myocardial ischemia. The arterial partial pressure of oxygen in 16 patients was 3.86 ± 0.84kPa. The arterial blood The oxygen saturation is 49.5 ± 13.3%. 22 cases were cured after treatment with oxygen and “crown ginseng tablets” or hyperbaric chamber, and the other 2 cases were recovered after 1 week return to plain. Electrocardiogram showed disappearance of myocardial ischemia and heart rate. Arterial oxygen partial pressure and oxygen saturation significantly increased compared with before treatment, the difference was significant (P <0.01). The author believes that: This is an idiopathic disease caused by plateau hypoxia, is a new type of plateau disease, tentatively named “plateau sinus node dysfunction.”
