This study was conducted to document the trend in arterial hypoxaemia and electrocardiographic (ECG) abnormalities on second to sixth night after acute myocardial infarction (AMI). Nineteen consecutive patients with AMI were monitored continuously during the night with a Holter tape recorder and a pulse oxymeter. Five patients had > 30 episodic oxygen desaturations of > or = 5%, and many patients had episodes with oxygen desaturations < 80% ranging from 46-61% (from 7/15-11/18) during the nights of monitoring. Constant hypoxaemia was found in 11-13% of the patients. Many patients had simultaneous occurrence of episodic hypoxaemia and episodic sinustachycardia, ST-deviation and arrhythmias, giving a summarized simultaneous occurrence of episodic hypoxaemia and ECG-abnormalities ranging from 13/18 (72%) patients on the third night to 7/15 (46%) patients on the sixth night. Episodic and constant hypoxaemia are thus common during the first week after AMI. Episodic hypoxaemia was associated with ECG-abnormalities in the majority of patients.
本研究旨在记录急性心肌梗死（AMI）后第二至第六晚动脉血氧不足和心电图（ECG）异常的趋势。连续19例AMI患者在夜间使用动态心电图记录仪和脉搏血氧仪进行持续监测。5例患者出现30次以上发作性氧饱和度下降≥5%，许多患者在监测夜间出现氧饱和度<80%的情况，范围为46%-61%（从7/15至11/18）。11%-13%的患者存在持续性低氧血症。许多患者同时出现发作性低氧血症和发作性窦性心动过速、ST段偏移及心律失常，发作性低氧血症和心电图异常同时出现的总结情况为，第三晚13/18（72%）的患者出现，第六晚7/15（46%）的患者出现。因此，发作性和持续性低氧血症在AMI后的第一周很常见。大多数患者的发作性低氧血症与心电图异常有关。
