本文测定了252名正常人的STI,确定了正常值范围,并认为在提出评定心功能的STI正常值时,在一定心率范围内,可以不必与心率、性别、年龄相校正。
In this paper, we measured the STI of 252 normal subjects and determined the range of normal values. We think that it is not necessary to correct the heart rate, sex, and age within a certain heart rate when the normal STI value of cardiac function is proposed.
