ABSTRACT
Objective To study the relationship between resting heart rate(RHR)and essential hypertension(EH).Methods 215 patients with EH and 82 healthy subjects underwent RHR detection.The relationship between RHR and the state of EH was analyzed.Results RHR in EH group was significantly higher than that in normal group[(78.9±9.1)bpm vs(69.5±10.9)bpm,P＜0.01)],RHR in different stages of EH was significantly different(F=21.280,P＜0.01,respectively),and increased with grades(P＜0.05 orP＜0.01).RHR in EH patients complicated with left ventricle hypertrophy(LVH)was higher than those with no LVH[(83.9±9.1)bpm vs (75.9±8.9)bpm,P＜0.01].There was positive correlation between RHR and LVH(r=0.8097,P＜0.01).Conclusion RHR is related to the development and progress of EH,and it may be one of the index for estimating the state of EH.
