急性心肌梗死早期低血钾与室性心律失常关系的临床研究

Clinical study on the relationship between hypokalemia and ventricular early acute myocardial infarction arrhythmia

目的：探讨急性心肌梗死及室性心律失常之间的关系。方法：选择确诊为AMI的患者126例，于入院即刻抽血测血清钾浓度，检测室性心律失常发生情况。结果与结论：126例患者血清钾浓度〈3．5mmo1／L者61例（48．4％），其中发生室性心律失常43例（70．5％）；血钾浓度在3．5～4．5mmol／L之间26例。其中发生室性心律失常8例；血钾农度〉4．5mmo1／L39例，其中发生室性心律失常10例（25．6％）。各组室性心律失常发生率比较差异有显著性x^2=9．174，P〈0．05。

Objective： To investigate the relationship between acute myocardial infarction and ventricular arrhytbmia. Methods： 126 patients diagnosed as AMI patients, at admission were measured in the serum potassium concentration, detection of ventricular arrhythmia. Results and conclusion; Of 61 cases, 126 cases of ser-um potassium concentration in patients with〈3.5mmol＇ L （48. 4 % ）, 43 cases of ventricular arrhythmia （70. 5% ） ;the serum potassium concentration in the range of 3.5 - 4. 5mmol＇L in 26 cases, 8 cases of ventricular arrhythmias;potassium concentration in blood of 〉4. 5mmol＇L39 patients, 10 cases of ventricular arrhythmia （25.6%）which. There were ventricular arrhythmia rate had significant difference on x^2 = 9. 174, P〈0.05.
