晚近应用多普勒超声记录右室流出道的流速曲线,测量右室的射血前期(PEP)、射血时间(ET)和加速时间(AT),计算其相互间的某些比值,以预测肺动脉平均压(PAMA)、收缩压和舒张压。本文分析心功能不全对上述参数及其预测准确性的影响,并试图建立一种新的指标。方法:从82例受试者中剔除透声条件不佳者5例,余77例包括2组受试者。以32(男23、女9)例健康成人为对照(组Ⅰ),年龄47±16岁。心脏病患者45(男21、女24)例(组Ⅱ),年龄48±13岁,其中17例以二尖瓣病变为主,8例以主动脉瓣病变为
Recent application of Doppler ultrasound recording of right ventricular outflow tract velocity curve, right ventricular preeclampsia (PEP), ejection time (ET) and acceleration time (AT), calculate the ratio between them to predict Mean pulmonary artery pressure (PAMA), systolic and diastolic blood pressure. This article analyzes the impact of cardiac dysfunction on these parameters and their predictive accuracy, and attempts to establish a new indicator. Methods: Five patients with poor sound transmission were excluded from the 82 subjects, and the remaining 77 patients included two subjects. 32 (male 23, female 9) healthy adults as control (group Ⅰ), aged 47 ± 16 years. 45 cases of heart disease (male 21, female 24) (group Ⅱ), age 48 ± 13 years old, of which 17 cases were mainly mitral valve disease, 8 cases of aortic valve disease
