根据心电图监测结果,将91例充血性心力衰竭(CHF)患者分为普通组(30例)和室性心律失常组(61例)。后者又分利尿剂和非利尿剂两个亚组。对照组25例。测定当天红细胞镁、血清镁和尿镁。结果显示:①心律失常组红细胞镁和血清镁明显低于普通组(P<0.05);②利尿剂亚组红细胞镁和血清镁明显低于非利尿剂组(P<0.05);③心律失常组中红细胞镁减低者易发生恶性室性心律失常(P<0.05)。本文提示,CHF伴室性心律失常时缺镁是不容忽视的,应用利尿剂时则更易发生低镁。
According to the results of electrocardiogram monitoring, 91 patients with congestive heart failure (CHF) were divided into general group (30 cases) and ventricular arrhythmia group (61 cases). The latter is divided into two sub-diuretics and diuretics. Control group of 25 cases. Red blood cells were measured on the day of magnesium, serum magnesium and urinary magnesium. The results showed that: (1) The levels of magnesium and serum magnesium in erythrocytes in arrhythmia group were significantly lower than those in normal group (P <0.05); ②The levels of magnesium and serum magnesium in erythrocyte subgroup were significantly lower than those in non-diuretic group (P <0.05) Erythrocyte magnesium decreased susceptibility to malignant ventricular arrhythmias (P <0.05). This article suggests that CHF with ventricular arrhythmias magnesium deficiency can not be ignored, the use of diuretics are more prone to low magnesium.
