目的探讨心肌梗死(myocardial infarction MI)患者心率减速力(Deceleration capacity of rate DC)检测结果的临床意义。方法选自我们医院MI患者40例和同期非心肌梗死患者30例。检测DC值并进行比较。结果 MI组DC值低于对照组。p<0.05。DC值越低,发病率越高的趋势。结论 MI组DC值明显低于对照组,DC检测方法技术易行,检测结果可靠,敏感性高,特异性稳定而一致,优于LVEF和SDNN的检测。值的临床推广。
Objective To investigate the clinical significance of Deceleration capacity of rate DC (DC) in patients with myocardial infarction MI. Methods Forty patients with MI in our hospital and 30 patients with non-myocardial infarction in the same period were enrolled. Detect DC values and compare. Results The DC value in MI group was lower than that in control group. p <0.05. The lower the DC value, the higher the incidence of the trend. Conclusions The DC value in MI group is obviously lower than that in control group. The DC detection method is technically easy, reliable, sensitive, stable and consistent, which is better than LVEF and SDNN. Value of clinical promotion.
