Medical Definition of Exercise cardiac treadmill
Exercise cardiac treadmill: A machine used to obtain a continuous
electrocardiogram (EKG, ECG) recording of the heart as a patient performs
increasing levels of exercise. An
exercise cardiac treadmill permits the
detection of abnormal heart rhythms (arrhythmias) and provides a screening test
for the presence of narrowed arteries of the heart (coronary arteries).
Narrowing of these arteries can limit the supply of oxygenated blood to the
heart muscle during exercise.
