ABSTRACT
Objective To explore the clinical value of Holter heart rate turbulence in diagnosis of patients at high risk for coronary heart disease.Methods 110 patients with suspected coronary artery disease,according to the results of coronary angiography (CAG),were divided into CAG positive group (67 cases) and CAG negative group (43 cases).Heart rate turbulence and heart rate variability were analyzed in two groups.The atrial fibrillation,atrial flutter,and pseudo-differential interference were removed,the qualified ventricular contraction was selected.Two parameters of HRT,the initial shock value (TO) and turbulence slope value (TS) were calculated.Results The average value of TO and TS was (0.36 ± 0.15) %,(1.98 ± 0.52) ms/RR in positive group,those in the negative group were (-0.87 ± 0.36) % and (4.83 ± 0.65) ms/RR,there were statistically significant differences between two groups (t =1.953,1.976,all P < 0.05).After 1 year follow-up,9 cases (13.44%) died in positive group,2 cases (4.65%) died in negative group,the difference was statistically significant (x2 =5.476,P < 0.05).Conclusion The heart rate turbulence with dynamic cardiogram can help to early diagnose the patients at high risk of coronary heart disease.It was important to improve the survival rate of patients.The method is simple,inexpensive,effective,which is worth promoting in the clinic.
