目的观察心力衰竭与室性心律失常的关系。方法38例同时具有高血压病、心阻抗图和彩色多普勒所测EF值<50%及24h动态心电图记录室性心律失常患者,以利尿、扩血管为基本药物,连续治疗4～6周,观察EF值与室性心律失常的变化。结果治疗后32例EF值>50%,其中25例室性心律失常全部消失;7例和EF值仍<50%的6例合计13例,占34.2%,室性心律失常发生率较治疗前减少,差异有统计学意义(t=4.9,P<0.001),每例室性早搏(143.8±66.1)次,较治疗前的(2561.6±1257.2)次减少,差异有统计学意义(t=5.8,P<0.001)。结论提示随心功能改善,心力衰竭时引起的心肌生理异常改变具有可修复性,改善心功能可治疗室性心律失常及预防室性心律失常的发生。
Objective To observe the relationship between heart failure and ventricular arrhythmia. Methods 38 patients with hypertension, heart resistance and color Doppler measured EF value <50% and 24h Holter recording ventricular arrhythmia patients with diuresis, vasodilator as the basic drugs, continuous treatment of 4 to 6 weeks , Observe the changes of EF and ventricular arrhythmia. Results After treatment, 32 cases of EF value> 50%, of which 25 cases of ventricular arrhythmia all disappeared; 7 cases and the EF value is still <50% of the 6 cases a total of 13 cases, 34.2%, ventricular arrhythmia than before treatment (T = 4.9, P <0.001). The number of ventricular premature beats in each case was 143.8 ± 66.1, which was significantly lower than that before treatment (2561.6 ± 1257.2), the difference was statistically significant (t = 5.8 , P <0.001). The conclusions suggest that the improvement of cardiac function, heart failure caused by myocardial abnormal changes can be repaired, improve cardiac function can be treated ventricular arrhythmias and prevent the occurrence of ventricular arrhythmia.
