内容提要:本文对70例成人行经食道心房调搏负荷试验,并以动态心电图监测下踏车运动试验作对照.结果表明,以心电图ST参数为标准时两试验对冠心病诊断价值相近;非ST参数△RST和△QTc的敏感性和特异性均低于ST参数.对影响心房夺获的主要因素及试验的临床应用价值进行了讨论.
Abstract: In this paper, 70 adult adults underwent transthoracic atrial pacing load test and ambulatory electrocardiogram (ECG) treadmill exercise test as a control.The results show that two parameters of electrocardiogram (ST) △ RST and △ QTc sensitivity and specificity are lower than the ST parameters.An influencing atrial seizure of the main factors and the clinical value of the trial were discussed.
