Abstract Objective To investigate the correlation of glycated hemoglobin (HbA1c) and arrhythmia in patients with type 2 diabetes. Methods 396 cases of inpatients with type 2 diabetes were enrol ed from February 2014 to May 2015. They were divided into group A (HbA1c≥7.0%, n=124) and group B (HbA1c<7.0%, n=272) based on HbA1c at admission. The relevant parameters were analyzed and compared between the two groups. Logistic regression analysis was performed to determine the relationship between HbA1c and arrhythmia. Results Triglyceride (TG), fasting plasma glucose(FPG), HbA1c, the homeostasis model assessment of insulin resistance were higher in group A than in group B(P<0.05 or 0.01). The incidence of total arrhythmias, supraventricular arrhythmias, ventricular arrhythmias and atrioventricular block in group A were significantly higher than in group B(al P<0.01). Logistic regression analysis showed that HbA1c was independently related with arrhythmia (OR=2.478,95% CI: 1.632~5.145, P<0.01). Conclusion HbA1c is related with arrhythmias in patients with type 2 diabetes, and may be an independent risk factor for arrhythmia.
