Pertinence analysis in heart rate change and tilting time of base tilt table test positive patients with age

Abstract

Objective To explore the relationship of heaa rate change,tilting times and age of base tilt table test(B1Trr)positive patients in test processes.Methods Analyzed retrospectively BTTT positive patients 116 eases.According to age,they were divided into early youth group(group A)37 cases,youth group(group B)30 cases,middle age group(group C)38 eases,old age group(group D)11 cases.Compared with each group heart rate in lying position,tilting position,when symptom was broken and tilting time were related to age.Results Heart rate in lying position:group A was the fastest than others,P＜0.01;There was no significant difference among others,P＞0.05.The fastest heart rate in tilting position:there were no significant difference in group C and D,P＞0.05;There were significant difference among others,P＜0.01.When symptom was broken:the heart rate of group C Was slowest among groups,P＜0.0l;There were no significant difference among other groups,P＞0.05.Tilting time:there was significant difference in each group,P＜0.01.Postural orthostatic tachycardia(POT):group A 16 cases,group B 11 cases,group C 8 cases,group D 2 cases.Postural orthostatic hypotension(POH):there were 2 cases in group D.Conclusions①Heart rate in lying position and tilting position are inverse ratio to age,tilting time is direct ratio to age;②Middle age with syncope history is higher danger group of heart sudden death;③part of base tilt table test positive response in aged patient is false positive.
