Abstract:
Objective To assess the characteristics of heart rate turbulencer (HRT) in elderly patients with decreased left ventricular diastolie function.Methods 40 patients were divided into two groups:20 patients with enlarged left atrium and 20 patients without enlarged left atrium.20 healthy people were selected as controls. Turbu1ence onset (TO) and turbulence slope (TS) were measured,and correlation was analyzed between TO,TS and the E/A,index of Macruz and heart rate variability (HRV).Results TO was higher (P<0.05) and TS was lower in patients (P<0.01),TO was higber in patients with enlarged left atrium than in with out enlarged lef atrium people (P<0.05) and TS was lower (P<0.01).TO was positively (P<0.01) and TS Was negatively (P<0.05),correlated with the index of Macruz.TO Was negatively (P<0.05) and TS was positively (P<0.05) related to SDNN and SDANN.Conclusion HRT can be used as a potential risk predictor in decreased left ventricular diastolic function patients.
