| treadmill, exercise | A continuous EKG recording of the heart as the patient performs increasing levels of exercise. In addition to detecting abnormal heart rhythms (arrhythmias), the exercise treadmill is a screening test for the presence of narrowed coronary arteries that can limit the supply of oxygenated blood to the heart muscle during exercise.

| treadmilling | <cell biology> Name given to the proposed process in microtubules in which there is continual addition of subunits at one end and disassembly at the other, so that the tubule stays of constant length, but individual subunits move along. Could in principle be used as a transport mechanism, although this is not currently favoured as a possibility. Has also been suggested for microfilaments. (19 Jan 1998) |
| exercise treadmill | A continuous EKG recording of the heart as the patient performs increasing levels of exercise. The exercise treadmill permits the detection of abnormal heart rhythms (arrhythmias) and provides a screening test for the presence of narrowed arteries to the heart (coronary arteries). Narrowing of these arteries can limit the supply of oxygenated blood to the heart muscle during exercise. (12 Dec 1998) |
