This study examined the effects of the male's position during sexual intercourse on heart rate and blood pressure responses. Eight men, 24 to 40 years of age, were studied in the privacy of the bedroom during sexual activity with their wives. The ECG was monitored continuously by portable ...
Your pulse rate is the number of times your heart beats per minute12.A "normal" pulse rate depends on your age and current level of fitness2.The average resting heart rate for most adults, including senior citizens, is between 60 and 100 beats per minute1.Young children tend to have high...
What is normal heart rate variability (HRV) range? See how HRV changes by age and gender and calculate your normative HRV scores.

If the stroke volume is 80 ml and the heart rate 120 bpm, what is the cardiac output? Is this more or less than what is considered normal for a healthy adult? What will a high level of testosterone in circulation do? What is meant by "blood alcohol level" (also known as "blood alc...
Heart Rate and Gender There’s a myth that you can predict your child’s sex by listening to its heartbeat in the womb. The notion is that male and female fetuses have different heart rates. Female fetuses, themyth holds, have heart rates of 140 bpm or higher, while male fetuses’ hav...
This study analyzed Heart Rate Variability in a large sample of active young subjects within a narrow age range (18 to 25), using time and frequency domain methods and a Poincaré plot. Heart rate was recorded (beat to beat) for 30 minutes at rest in 200 healthy subjects divided into 4 ...
A normal heart rate depends on a person's gender, age, and fitness, but generally speaking, adults should have a resting heart...
Heart rate variability (HRV), the analysis of beat-to-beat changes in heart rate, is a noninvasive indicator of autonomic tone that might be useful in the identification of patients who are at risk for weaning difficulty due to underlying cardiac dysfunction. The authors describe HRV and ...
The reproducibility of the heart rate response to the Valsalva manoeuvre was assessed in 12 young normal subjects who each repeated the manoeuvre 10 times. The length of the RR intervals before, during, and after each Valsalva manoeuvre was measured from an electrocardiogram and the changes expresse...
