To the Editor: In their article on heart-rate recovery afterexercise as a predictor of mortality (Oct. 28 issue),1 Coleet al. did not clearly define the "cessation" of exercise intheir study, since there was a cool-down period that includedexercise. Did they mean the cessation of exercise accordingto the Bruce protocol or the cessation of the cool-down period(which was at least two minutes long)?
