This study compared the ventilatory threshold with the double-product break point in 104 patients with cardiovascular disease during ramp treadmill testing. The high correlation (r = 0.81) between the double-product break point and the ventilatory threshold, even in patients taking beta blockers, suggests the former method is a viable noninvasive alternative for identifying the anaerobic threshold in patients with cardiovascular disease, particularly when expired gas analysis is not appropriate or available.
本研究在104例心血管疾病患者进行斜坡式跑步机测试期间，比较了通气阈值与双乘积断点。双乘积断点与通气阈值之间存在高度相关性（r = 0.81），即使是服用β受体阻滞剂的患者也是如此，这表明前一种方法是识别心血管疾病患者无氧阈值的一种可行的非侵入性替代方法，特别是在呼气气体分析不适用或无法进行时。
