title: [Episodic hypoxemia and coinciding ECG changes after acute myocardial infarction].
abstract: 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.
