Why the study?
Do asymptomatic young men with primary T-wave aberrations have altered sympathetic activity and blood pressure responses to stress compared to matched controls?
Do asymptomatic young men with primary T-wave aberrations have altered sympathetic activity and blood pressure responses to stress compared to matched controls?
Primary T-wave aberrations in asymptomatic young men may be a marker of increased sympathetic activity and elevated systolic blood pressure, sharing similarities with borderline hypertension.

May link T-wave aberrations to sympathetic overactivity and higher BP in young men; hypothesis-generating and should not yet change practice.
Twelve asymptomatic young men with 'primary' T-wave aberrations in the electrocardiogram (group T) and 13 matched controls were subjected to a mental stress test, isometric exercise and a cold pressor test. 2. Plasma catecholamines and haemodynamics were studied. 3. Group T had signs of increased sympathetic activity at rest and enhanced sympatho-adrenal reactivity during stress. 4. Systolic blood pressure was consistently elevated in group T. 5. The T-wave aberrations may be explained by the increased sympathetic activity. 6. Several similarities exist between group T and borderline hypertensive subjects.
