Clinical Usefulness of Response Profiles to Rapidly Incremental Cardiopulmonary Exercise Testing
Figure 14
Heart rate response after incremental exercise in a healthy control and a patient with pulmonary arterial hypertension (PAH) of same age and gender (both females aged 31). Note the delayed recovery up to the 5th minute after-exercise in the patient compared to the control. HRR1 min ≤ 18 bpm after cycle ergometer exercise test has recently been found an independent predictor of mortality in these patients [28].
