应用经食道心房调搏心负荷进行正常人和冠心病人心脏收缩时间间期(STI)测定。结果表明:1.正常人组调搏前后各指标均值在正常范围内。冠心病组调搏前均值不正常,调搏后异常更为显著。2.正常组在调搏前后出现指标异常者不多,而冠心病组指标异常例数调搏后较调搏前均增加1倍以上,使敏感性大大提高,从而使早期或潜在的心功能障碍得以揭示。并讨论其优点和尚需研究注意的问题。
Application of transesophageal atrial pacing cardiac load in normal subjects and patients with coronary heart systolic time interval (STI) determination. The results showed that: 1. The mean value of each index before and after pacing in normal group was within the normal range. Coronary heart disease group before pacing is not normal, abnormal pacing more significant. In the normal group, there were not many abnormal indexes before and after pacing, while the number of abnormal indexes in CHD group was more than double that before pacing, which greatly increased the sensitivity, so that the early or potential cardiac function Obstacles can be revealed. And discuss its merits and problems to be studied.
