Heart rate variability and heart rate in healthy volunteers. Is the female autonomic nervous system cardioprotective? Eur. Heart J. 19, 1334–1341 (1998). Article CAS Google Scholar Murphy, E., Amanakis, G., Fillmore, N., Parks, R. J. & Sun, J. Sex differences in metabolic ...
On physical examination, the blood pressure was 130/73 on left and 135/75 on right, heart rate 80 bpm regular, and body mass index 34 kg/m2. The only notable physical finding was of a left carotid bruit. Handheld echocardiogram showed normal left ventricle (LV) systolic function and no ...
The time constants of single expo- nential fits for the O2pulse data were not affected by work rate. Moreover, there were no significant differences observed between adults and children. Although there were small differences in the magnitude of the O2pulse, the time course of this response ...
This study sought to define the effects of age and gender effects on the normal range of time domain heart rate variability (HRV) over nine decades in healthy subjects. Background. Low HRV is considered an independent marker of mortality risk. However, the age-related decline in HRV may ...
Much like resting heart rate, several factors can impact HRV. These include the following: Sex and HRV Healthy women have a lower HRV when compared to their healthy male counterparts, especially before the age of 30. The difference between genders gradually decreases until it stabilizes after 50...
How Does Heart Rate Variability Work? Your heart rate is governed by the balance of the sympathetic and parasympathetic nervous systems, explainsNino Isakadze, MD, a cardiac electrophysiology fellow at Johns Hopkins Medicine in Baltimore. These systems are part of the autonomic nervous system, which...
During IHG, men presented a stronger absolute increase in heart rate, diastolic BP, left ventricular (LV) volumes and cardiac output than women, even after adjustment for covariables. In adjusted continuous and categorical analyses, age correlated positively with the increase in systolic BP and ...
Circulatory changes during pregnancy may result in adverse maternal and foetal outcomes in women with heart disease. Circulating blood volume, cardiac output and heart rate increase progressively after the first trimester, and worsen during the uterine contractions of labour and subsequent delivery [1]....
Heart rate variability (HRV) is associated with blood pressure levels; however, very few studies have correlated HRV to lifestyle in the general population. We investigated 1418 men and 2040 women aged 40–74 years and measured the HRV indices in the time and frequency domains using a 5-min...
