本文报道经食管心房调搏前后的左室舒张功能改变及其意义。采用心尖搏动图的 a/H、a/D、TARTi、DATi 等指标。调搏以160次/min 为中止点。观察正常人40例,冠心病68例。结果,各指标在正常人调搏前后无明显差别,在冠心病者则差异显著,且冠心病者调搏后各异常指标的出现率较调搏前增加一倍以上,说明本法可提高冠心病者异常指标的检出率和敏感性,使其早期或潜在的舒张功能障碍得以揭示出来。
This article reports the changes of left ventricular diastolic function before and after transesophageal atrial pacing and its significance. Using apex beat chart a / H, a / D, TARTi, DATi and other indicators. Pace to 160 times / min as a stop point. 40 cases were observed normal, 68 cases of coronary heart disease. The results showed that there was no significant difference in each index before and after pacing in normal people, but significant difference in those with coronary heart disease. The incidence of abnormal indexes after pacing in CHD patients more than doubled than that before pacing, The detection rate and sensitivity of the abnormal index of heart disease make it reveal the early or potential diastolic dysfunction.
