Why the study?
Does practolol alter haemodynamic and electrocardiographic responses to upright exercise in patients with coronary heart disease?
Does practolol alter haemodynamic and electrocardiographic responses to upright exercise in patients with coronary heart disease?
Practolol alters haemodynamics and reduces ST segment depression during exercise in coronary heart disease, indicating that ST depression may no longer reliably reflect myocardial ischaemia after beta blockade.
No takes yet. Share an insight, caveat, or question.
May question ST depression reliability as ischemia marker after beta blockade; leaves open diagnostic implications for exercise testing.
Rousseau et al. (1973) studied this question.
