ABSTRACT
Objective To discuss the significance and alteration of heart rate turbulence (HRT) of diabetics with ventricular premature beats of coronary heart disease (CHD). Methods 107 patients were chosen and divided into DM group(n=30), CHD group (n=32)and normal group(n=45).The turbulence onset(TO)and turbulence slope(TS) were calculated and analyzed. Results For the diabetics with ventricular premature beats, TO value was higher and TS value was lower than the normal group(all P<0.05).The value of TO and TS of the diabetics with ventricular premature beats were similar to those of CHD(P>0.05). Conclusions HRT can be used to estimate the integrality and stability of cardiac autonomic nerve function for the diabetics and it is an important factor for diagnosis.
