Answer

Cardiopulmonary exercise testing is a sensitive test for identifying and quantifying the extent of pulmonary involvement. Cardiopulmonary exercise testing also may suggest cardiac involvement that otherwise is not evident. Impaired heart rate recovery during the first minute following exercise has been shown to be an independent predictor for cardiovascular and all-cause mortality, [1] and it may identify patients who are at high risk for ventricular arrhythmias and sudden death.
