title: Exercise ECG testing using different protocols in asymptomatic healthy young subjects.
abstract: Thirty four healthy young male subjects performed symptom limited exercise on Bruce protocol on treadmill machine. Hyperventilation induced labile repolarisation ST-T abnormalities were observed in 2 whereas exercise induced ST changes (upsloping ST depression in 4 and horizontal ST depression in 1) were observed in 5 additional candidates. Changes were unaccompanied by symptoms or signs and quickly reverted back to normal within 30 sec. of cessation of exercise and hence were 'probable false positives'. Sixty-eight age and sex matched volunteers (including former 34) when exercised on Master's stepper, failed to reveal any change probably due to the lack of continuous ECG monitoring device.
