Why the study?

What are the mechanisms of QRS voltage changes on ECG during exercise in healthy subjects?

Population

14 healthy subjects (7 men and 7 women) not older than 35 years

Comparison

Stepwise increasing exercise sessions with two… vs Comparison between different exercise modalities

What are the mechanisms of QRS voltage changes on ECG during exercise in healthy subjects?

Population

14 healthy subjects (7 men and 7 women) not older than 35 years

Intervention

Stepwise increasing exercise sessions with two upper limbs and one lower limb, and exercise with vertical and horizontal torso position

Comparator

Comparison between different exercise modalities (two arms vs one leg, vertical vs horizontal torso position)

Outcome

Changes of QRS waves (S-wave amplitude in left chest leads) during exercise and their relationship with peak systolic arterial pressuresurrogate

Exercise-induced S-wave augmentation on ECG in healthy subjects is dependent on systolic blood pressure rather than heart position, size changes, or exercise load.
