目的探讨在有器质性心脏病尤其伴充血性心力衰竭(CHF)室性心律失常(VA)的关系。方法30例CHF患者进行心电图及Holter检查,同日测量血清钾、镁浓度。超声心动图观测左室射血分数(EF值)及室壁运动情况,并加以分析。结果①CHF患者心律失常发生率90%。②VA低于LownⅢ级者的EF显著高于LownⅢ级以上者,差异有非常显著性(P<0.01)。④室壁运动异常组发生高于无室壁运动异常组,二者差异有统计学意义(P<0.05)。⑤VA中血清钾离子浓度多在正常低限或低于正常且多合并低镁。结论器质性心脏病尤其伴充血性心力衰竭(CHF)中(VA)发病率很高,治疗CHF时心律失常的目的是缓解症状和改善预后。
Objective To explore the relationship between organic heart disease and ventricular arrhythmias (VA) in patients with congestive heart failure (CHF). Methods Thirty CHF patients underwent electrocardiogram and Holter examination. The serum potassium and magnesium concentrations were measured on the same day. Echocardiography left ventricular ejection fraction (EF value) and wall motion, and analyzed. Results ① The incidence of CHF in patients with arrhythmia 90%. (2) The EF of LVEⅢwas significantly higher than that of Lown Ⅲ, the difference was significant (P <0.01). ④ The abnormal wall motion group occurred more than the non-wall motion abnormal group, the difference was statistically significant (P <0.05). ⑤ VA serum potassium concentration in the normal low or lower than normal and more low magnesium combined. Conclusion The incidence of organic heart disease, especially congestive heart failure (CHF), is high. The purpose of arrhythmia in the treatment of CHF is to relieve the symptoms and improve the prognosis.
