Abstract:
Objective To observe the changes of the heart rate turbulence(HRT)in patients with isolated systolic hypertension(ISH).Methods 85 patients with ISH,80 patients with common hypertension and 58 control subjects were investigated.Turbulence onset(TO)and turbulence slope(TS)were recorded of 24 hours dynamic electrocardiogram.Results The difference of HRT in the three groups was significant(P＜0.01).The values of TO and TS was significantly higher in common hypertension group and ISH group than in control group(P＜0.05);TS was significantly lower in ISH group than in common hypertension group(P＜0.05),but the difference of TO between ISH group with common hypertension group was not obvious.Conclusion The HRT in patients with primary hypertension is significantly lower,which is more significant in patients with ISH than in patients with common hypertension.It suggests that the cardiac autonomic nerves dysfunction perhaps has an important influence on development of hypertension and its prognosis.
