Abstract:
Objective To study the related factors of arrhythmia in patients with different types of coronary heart disease(CHD).Methods 330 patients with coronary heart disease were studied,including acute coronary syn-drome(ACS)of 210 cases (ACS group)and chronic ischemic syndrome (CIS)in 120 patients(CIS group).The slow arrhythmia occurrence types were detected by the dynamic electrocardiogram(DCG),and analyzed the correlation of different types of CHD occurrence of arrhythmia and serum brain natriuretic peptide BNP,left ventricular ejection fraction(LVEF),LVDD,serum potassium level and the number of diseased coronary artery.Results There were no significant differences in the incidence of atrial arrhythmias and ventricular arrhythmias between the two groups(χ2 =0.982,2.136,all P>0.05),and there were no significant differences in the proportion of all kinds of arrhythmia(all P>0.05).ACS patients with arrhythmia types and BNP and LVEF,LVDD level and coronary artery lesion counts had no significant differences(χ2 =0.044,0.061,0.347,all P>0.05).Related to the type of arrhythmia and serum potassium levels,patients in a low blood potassium levels,the incidence of ventricular arrhythmias increased signifi-cantly(χ2 =4.376,P<0.05).And increased BNP level,LVEF decreased and LVDD,atrial arrhythmias occurred rate were significantly higher than those of ventricular arrhythmias(all P<0.05),gradually increased with the number of diseased coronary artery,cardiac arrhythmia occurred rate increased.CIS patients arrhythmia type with BNP and LVEF,LVDD level (all P <0.05 ).And elevated BNP levels,LVDD and LVEF decreased levels increased and ventricular arrhythmia occurrence rate was significantly higher than that of the atrial arrhythmia(χ2 =5.811,5.968, 4.060,all P<0.05).The rhythm types of arrhythmia and serum potassium levels and coronary artery disease variable count had no significant difference(χ2 =2.336,P>0.05).Conclusion The arrhythmia types of ACS are irrelevant with BNP,LVEF,LVDD and coronary artery lesions,and hypokalemia patients prone to ventricular arrhythmia.CIS is related with BNP increase,LVEF decrease and LVDD increase,prone to ventricular arrhythmias,low blood potassium patients prone to atrial arrhythmias.
