ST-segment changes in normal men during ambulatory electrocardiography.
24-hour ambulatory monitoring was performed on 46 healthy men. The ECG analysis system employed a digital filter implemented in software to obtain satisfactory low frequency response. The 46 subjects were aged between 18 and 63. Of the 30 subjects aged 30 and under, 13 had episodes of ST elevation, 3 had episodes of ST elevation and depression and 3 had episodes of ST depression. In the 16 subjects aged over 30, 3 had episodes of ST elevation. During ambulatory electrocardiographic monitoring of healthy men aged 30 and under, ST-segment changes were a common finding.
