the emergency severity index (esi) is a five-level triage system that has shown promising reliability and validity. according to esi algorithm, in the presence of danger zone respiratory rate (rr), heart rate (hr) or oxygen (o2) saturation, patients should be up-triaged from esi level 3 to 2 hence, the current study aimed to investigate the value of the measurement of vital signs in predicting ...

Inability to reach 85% of the predicted maximal heart rate for age during exercise stress testing (chronotropic incompetence) has been considered indicative of an uninterpretable or inadequate test. A new study from the Cleveland Clinic suggests that a submaximal heart rate response to exercise may be a significant independent risk factor for all-cause and cardiovascular death in individuals wi...
