临床上常用的左心衰无创性检查很多,如x线胸片上肺郁血程度,心/胸比,心音图S_3,PEP/LVET比,V_1ptf等。对这些检查结果的真正价值及其定量或半定量的意义,争论很多。我们用Swan-Ganz漂浮导管在病人床边测定各级心功能病人的肺动脉舒张末期压(PAEDP),做为心衰病人严重程度的一个定量指标;并与这
Commonly used in clinical noninvasive examination of many left heart failure, such as x-ray on the level of lung cancer, heart / chest, phonocardiogram S_3, PEP / LVET ratio, V_1ptf and so on. There is much debate about the true value of these test results and their quantitative or semi-quantitative significance. We measured the pulmonary end-diastolic pressure (PAEDP) in patients with various cardiac functions at the patient’s bed using a Swan-Ganz floating catheter as a quantitative indicator of the severity of heart failure; and with this
