Influence of atenolol on the relationship between heart rate and qt interval in patients with exercise‐induced myocardial ischemia

The aim of this study was to analyze the relationship between heart rate and QT interval (HR‐QT) during exercise in control subjects (Group A) and in patients with coronary artery disease (CAD) with effort angina and without previous myocardial infarction (MI) (Group B). The diagnosis of CAD was con...

Zusammenfassung:	The aim of this study was to analyze the relationship between heart rate and QT interval (HR‐QT) during exercise in control subjects (Group A) and in patients with coronary artery disease (CAD) with effort angina and without previous myocardial infarction (MI) (Group B). The diagnosis of CAD was confirmed by coronarographic examination. The correlation HR‐QT was significant (p
