BACKGROUND Genome-wide association studies have identified several genetic loci associated with variation in resting heart rate in European and Asian populations. No study has evaluated genetic variants associated with heart rate in African Americans. OBJECTIVE To identify novel genetic variants associated with resting heart rate in African Americans. METHODS Ten cohort studies participatin...

Background—Cardiopulmonary exercise testing is often used to evaluate exercise capacity in adults with congenital heart disease including women who are considering pregnancy. The relationship between cardiopulmonary exercise testing parameters and pregnancy outcome has not been defined. Methods and Results—We conducted a multicenter retrospective observational study of women with congenital hea...

Personality and heart rate variability (HRV) each are strong predictors of well-being, particularly cardiac health and longevity. The present study compares the changes in HRV during resting state in the Type ̳A‘ and Type ̳B‘ personalities. The personality of subjects is chosen according to Glazer questionnaire. In each of these two groups 30 males were taken. After general interview of these s...

conclusions the results showed that, compared to participants with normal weights, physiological and thermal perceptual responses were higher in overweight participants. therefore, overweight individuals should avoid hot/dry weather conditions to decrease the amount of heat strain. results in both groups, oral temperature, heart rate, and thermal perceptual responses increased during heat expos...

The M 1 muscarinic receptor antagonist pirenzepine in low doses decreases resting heart rate; this effect declines with age (Poller, U., G. Nedelka, J. Radke, K. Pönicke, and O.-E. Brodde. 1997. J. Am. Coll. Cardiol. 29:187–193). To study possible mechanisms underlying this effect, we assessed ( a ) in six young (26 yr old) and six older volunteers (61 yr old), pirenzepine effects (0.32 and 0.6...

IT IS WELL KNOWN THAT ATHLETES have a low resting heart rate, i.e., a resting bradycardia and heart rates below 30 beats/min have been reported (7). For example, Wikipedia states that the Tour de France cyclist, Miguel Indurain, had a resting heart rate of 28 beats/min when race fit. The resting bradycardia in athletes is most often attributed to high vagal tone, i.e., high parasympathetic nerv...
