目的探讨心率减速力值对肺心病右心衰竭恶性室性心律失常患者的预后分析。方法应用24 h动态心电图记录65例肺心病右心衰竭恶性室性心律失常患者组(观察组)接受电除颤器、电复律及相关药物救治措施和65例健康者组(对照组)的心率减速力值预后进行对比分析。结果 65例肺心病右心衰竭恶性室性心律失常患者组的病死率:DC值≥4.5ms 24h内为1.53%,2周内为3.07%,1年内为6.15%;DC值≤2.5ms 24h内为7.69%,2周内为10.76%,1年内为15.38%,各值比较p<0.05;65例对照组心率减速力各值中无死亡病例。结论肺心病右心衰恶性室性心律失常的存活率较低,病死率很高,对该类患者应立即采取电除颤器、电复律及相关药物救治措施,改善预后,降低死亡率。心率减速力值测定能定量、单独分析和测定迷走神经作用的强度,对肺心病心力衰竭高危人群筛选与预警具有较强的实用价值。
Objective To investigate the prognostic value of heart rate deceleration in patients with cor pulmonale of right heart failure with pulmonary heart disease. Methods A total of 65 patients with cor pulmonale of heart failure with right heart failure (observation group) were treated with defibrillators, electrical cardioversion and related drugs and 65 healthy volunteers (control group) with 24 h ambulatory electrocardiography Heart rate deceleration force prognosis for comparative analysis. Results The mortality of 65 cases of patients with cor pulmonale of heart failure with right ventricular failure of heart failure was 1.53% in DC ≥4.5ms, 3.07% in 2 weeks and 6.15% in 1 year, and DC value ≤2.5ms 24h Was 7.69%, 10.76% in 2 weeks and 15.38% in 1 year, p <0.05 in each value; there was no death in each value of 65 cases of control group. Conclusions The survival rate of malignant ventricular arrhythmia in patients with pulmonary heart disease is low and the mortality rate is very high. For such patients, the defibrillator, electrical cardioversion and related drugs should be taken immediately to improve the prognosis and reduce the mortality rate. Heart rate deceleration force value can be quantitative, separate analysis and determination of the strength of the vagus nerve function, screening and early warning of high-risk groups of patients with cor pulmonale heart failure have strong practical value.
