Does ageing affect the amount of muscle, fat, and collagen in the human sinoatrial node and internodal tracts?
The study demonstrates a significant age-related decline in muscle content within the human sinoatrial node and internodal tracts, which may contribute to age-related electrophysiological changes.
Davies et al. (1972) studied this question.
