Key result
Maximal exercise in healthy women induced unpredictable changes in R wave amplitude, indicating that R wave changes should not be used for the diagnosis of coronary disease in women.
Why the study?
What are the quantitative electrocardiographic changes during and after maximal exercise in healthy women?
Observational (n=116)
What are the quantitative electrocardiographic changes during and after maximal exercise in healthy women?
Exercise-induced changes in R wave amplitude are unpredictable in healthy women and should not be used for the diagnosis of coronary disease.
No takes yet. Share an insight, caveat, or question.
Unpredictable R wave shifts during exercise in healthy women caution against diagnostic use; leaves open prospective validation in clinical cohorts.
Deckers et al. (1990) conducted an observational in Healthy (n=116). Maximal exercise was evaluated on Electrocardiographic changes (P wave, QRS complex, ST segment, and T wave) during and after maximal exercise. Maximal exercise in healthy women induced unpredictable changes in R wave amplitude, indicating that R wave changes should not be used for the diagnosis of coronary disease in women.
