Why the study?
Does a single 40-mg oral dose of oxprenolol reduce tachycardias induced by mental stress, catecholamines, and exercise in normal people?

Small doses of beta-blockers like oxprenolol can suppress stress-induced tachycardia without significantly impairing the heart rate response to everyday exercise.

Supports selective low-dose beta-blockade for stress or catecholamine tachycardias with minimal exercise impact; confirms context-specific effects in healthy subjects.
