WebFeb 10, 1999 · Main outcome measures: Association of chronotropic incompetence, defined as either failure to achieve 85% of the age-predicted maximum heart rate or a low chronotropic index, a heart rate response measure that accounts for effects of age, resting heart rate, and physical fitness, with all-cause mortality during 2 years of follow-up. WebImpaired chronotropic response index (CRI) was defined as <80% age-adjusted HR during 6MWT. Abnormal HR recovery (HRR) was categorized as reduction in HR ≤ 12 beats/minute after the first minute of 6MWT cessation. Results: A lower CRI was associated with obstructive lung disease and lower estimated aerobic capacity. greenwich university maritime campus https://heavenly-enterprises.com
