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’ have heart rates below 14...

Reasons for high Heart Rate in Sports Pulse rate too low When an adult’s pulse rate is less than 50 to 60 beats per minute (bpm), it is called bradycardia. For children, other limits apply depending on their age.16 However, as a population-based cohort study published in 2016 suggests...
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...
Analysis of heart rate variation (HRV) has become a popular noninvasive tool for assessing the activities of the autonomic nervous system (ANS). HRV analysis is based on the concept that fast fluctuations may specifically reflect changes of sympathetic a
Cardiovascular magnetic resonance (CMR) enables assessment and quantification of morphological and functional parameters of the heart, including chamber size and function, diameters of the aorta and pulmonary arteries, flow and myocardial relaxation time

Here, for the first time, we provide comprehensive morphological analysis of a large cohort of normal hearts over a range of ages. The are striking differences between the male and female hearts. Whilst it is well recognized that the male heart is heavier than the female heart (de [8], [...
