Key result
Male sex was associated with significantly longer sinus cycle length (864 vs 824 ms, P<0.05) and QRS duration (90 vs 86 ms, P<0.005) compared to female sex.

How do sex and age affect electrocardiographic and cardiac electrophysiological properties in adults without structural heart disease?
p-value: p=<0.05
Intrinsic cardiac electrophysiological properties such as sinus cycle length, QRS duration, HV interval, and sinus node recovery time are significantly longer in men than women, independent of age.
Taneja et al. (2001) conducted an observational in No structural heart disease or preexcitation (n=354). Male sex vs. Female sex was evaluated on Sinus cycle length (SCL) (p=<0.05). Male sex was associated with significantly longer sinus cycle length (864 vs 824 ms, P<0.05) and QRS duration (90 vs 86 ms, P<0.005) compared to female sex.
