Background:Cardiac output reserve and exercise capacity are strong predictors of life expectancy. Chronotropic incompetence (CI) is the inability to reach an age appropriate maximum heart rate with exercise. CI reduces cardiac output reserve and exercise capacity, both of which increase all-cause mortality risk. x age in years).Results:The
