摘要
目的探讨自主神经活动在室性心律失常发生中的作用。方法分析无器质性心脏病室性心律失常Lown分级≥Ⅲ级37例 (A组 )、Ⅰ~Ⅱ级30例 (B组 )和对照组35例 (C组 )的三角指数 (TI)、最快心率、最慢心率及最快与最慢心率差值。结果 (1)A组TI比B组、C组显著降低 (P<0.05、0.01) ;A组最慢心率比C组非常显著增快 (P<0.01) ,最快与最慢心率差值比C组非常显著缩小 (P<0.01)。 (2)A组TI阳性率较B组、C组非常显著升高 (P<0.01)。结论副交感神经张力降低对室性心律失常的发生起着重要作用 ,TI降低与自主神经功能受损密切联系。
Objective To approach role of autonomic never system in mechanism of ventricular arrhythemia.Methods To analysed102patients data of triangular index(TI),highest heart rate,lowest heart rate and difference of highest and lowest heart rate,all of them had no structural heart disease.Thirtyseven of these patients belong to≥gradeⅢin Lown′s classes group(group A),30belong to gradeⅠandⅡin Lown′s classes group(group B)and35placebo(group C).Results(1)TI in group A is much lower than that in group B and group C(P<0.05,0.01),difference between highest and lowest heart rate in group A was smaller than group C(P<0.01),(2)Positive rate in group A was higher than those in group B and C(P<0.01).Conclusion Decreasing tension of parasympathetic nerves play an important role in occurrence of ventricular arrhythmia,decreasing of TI is connet with injury in autonomic nerve system.
