Effects of Repeated Work Tests and Adrenergic Beta‐blockade on Electrocardiographic St and T Changes
Why the study?
Do repeated work tests and adrenergic beta-blockade normalize functional ST and T changes on ECG compared to organic changes?

Subjects with different ECG changes but without any apparent organic heart disease, and patients with…

Implication
May aid differentiation of functional from organic ST-T changes via repeated exercise testing; leaves open prospective validation before clinical adoption.
Structured PICO
Do repeated work tests and adrenergic beta-blockade normalize functional ST and T changes on ECG compared to organic changes?
P
Population
Subjects with different ECG changes but without any apparent organic heart disease, and patients with organic heart diseases (coronary insufficiency and myocarditis).
I
Intervention
Repeated work tests (4-6 work tests over a period of 4-6 days) and adrenergic beta-receptor blockade
C
Comparator
Comparison between the effects of repeated work tests and adrenergic beta-receptor blockade
O
Outcome
Electrocardiographic ST and T changes at rest, in the standing position, and during and after worksurrogate
Repeated work tests or adrenergic beta-blockade can help differentiate between functional and organic ST and T wave changes on the electrocardiogram.
