Key result
Propranolol use did not affect ratings of perceived exertion during graded exercise testing soon after myocardial revascularization surgery, despite lowering heart rate.
Why the study?
Does propranolol affect ratings of perceived exertion during graded exercise testing soon after myocardial revascularization surgery?
Observational (n=86)
Does propranolol affect ratings of perceived exertion during graded exercise testing soon after myocardial revascularization surgery?
Propranolol lowers heart rate but does not alter ratings of perceived exertion during graded exercise testing soon after myocardial revascularization surgery.
No takes yet. Share an insight, caveat, or question.
Propranolol does not alter RPE soon after revascularization; leaves open beta-blocker effects on exertion perception in modern early rehab.
Squires et al. (1982) conducted an observational in Myocardial revascularization surgery (n=86). Propranolol vs. No propranolol was evaluated on Ratings of perceived exertion (RPE) during graded exercise testing. Propranolol use did not affect ratings of perceived exertion during graded exercise testing soon after myocardial revascularization surgery, despite lowering heart rate.
