|
|
Term
| subjects are more likely to attain a _____ o2 consumption and peak HR during treadmill test than during cycle ergometer test |
|
Definition
|
|
Term
| it is easier to obtain better quality ECG recordings and blood pressure measurements because |
|
Definition
| there is less movement of the patients arms and thorax |
