Why the study?
Does physical activity alter cardiac response and ectopy in sedentary elderly adults?
Does physical activity alter cardiac response and ectopy in sedentary elderly adults?
Usual daily activities and aerobic walking produce expected chronotropic responses without triggering ectopy in healthy, sedentary older adults.
No takes yet. Share an insight, caveat, or question.
May support activity safety in healthy sedentary elderly; hypothesis-generating and requires prospective validation in higher-risk groups.
Roberts et al. (1996) studied this question.
