Should the attainment of predicted heart rate maximum be used as an exercise test end point?
Age predicted maximum heart rates based on the formula 220-age have long been used in fitness and clinical settings to gauge exercise intensity and predict exercise test end points. Exercise stress tests have in some cases been routinely terminated based on the attainment of this equation, despite recommendations that age predicted maximum heart rates should not be used as an exercise test endp...
متن کاملRESPONSES OF OXYGEN CONSUMPTION, HEART RATE AND PERCEIVED EXERTION TO CRUTCH WALKING: A COMPARISON BE TWEEN PAR APLEGIC AND ABLE-BODIED SUBJECTS
In this study, 10 normal volunteers and 5 sports-trained paraplegics with lesions between T6 and L2 were studied whilst walking with axillary crutches and knee-anlde-foot orthoses. All subjects walked at their preferred speed on a figureof- eight track. Normal subjects also walked at slower and faster speeds. Oxygen consumption, heart rate and rating of perceived exertion were measured. In...
متن کاملHeart Rate Variability as an Index of Regulated Emotional Responding
The study of individual differences in emotional responding can provide considerable insight into interpersonal dynamics and the etiology of psychopathology. Heart rate variability (HRV) analysis is emerging as an objective measure of regulated emotional responding (generating emotional responses of appropriate timing and magnitude). This review provides a theoretical and empirical rationale fo...
متن کاملHeart rate variability as a predictor of sudden cardiac death.
Different noninvasive approaches have been developed for risk stratification of patients with myocardial infarction and heart failure with aim to select patients at high risk of sudden cardiac death who might mostly benefit from preventive therapy. Reduced heart rate variability (HRV) was a strong predictor of mortality in myocardial infarction and heart failure in early studies. However, in th...
متن کاملHEART RATE: A PREDICTOR OF EARLY MORTALITY IN PATIENTS WITH MYOCARDIAL INFARCTION
A number of epidemiologic studies have reported a positive relationship between heart rate, cardiovascular disease and mortality. To examine the correlation between heart rate and mortality after acute myocardial infarction (AMI), 2147 patients hospitalized in coronary care units in Isfahan were investigated in a cross-sectional study. Their heart rate was measured according to an electroca...
