Abstract:
Objective To research into the relationship between heart rate variability (HRV) and QT dispersion(QTd) in patients with type 2 diabetes mellitus(T2DM) complicated with coronary heart disease(CHD).Methods In the research 30 patients with type 2 diabetes mellitus complicated with CHD were classified as group A,33 patients with T2DM as group B and 21 normal healthy persons as controlgroup,group C.24-hour time domain and 24-hour frequency domain parameters of HRV were recorded by holter ECG and analysed through computer.A standard 12-lead synchronous electrocardiogram was used to measure QT interval and QTd.Results (1)The research showed that all parameters of HRV in group A were less than those in group B and group C (P
