作者在症状限制极量卧式踏车心肺运动试验的同时行创伤血流动力学监测,旨在研究运动心输出量与耗氧量(VO_2)的关系。12例受试者均为慢性充血性心力衰竭(CHF)患者。结果表明,静息血流动力学参数与最大耗氧量(VO_(2max))无显著相关,提示静息心功能难以准确预测慢性 CHF 患者的运动耐量。经线性回归分
The authors performed traumatic hemodynamic monitoring at the same time as limiting the cardio-pulmonary exercise test of extreme horizontal treadmill treadmill exercise to study the relationship between cardiac output and oxygen consumption (VO2). All 12 subjects were chronic congestive heart failure (CHF). The results showed that resting hemodynamic parameters and maximum oxygen consumption (VO_ (2max)) were not significantly correlated, suggesting that rest heart function is difficult to accurately predict the exercise tolerance of patients with chronic CHF. The linear regression points
