Comparative StudyThe clinical use of supine left lateral leg cycle ergometry for exercise electrocardiographic testing in women, as used in exercise echocardiography.
Two-dimensional exercise echocardiography is commonly performed in the supine (SUP) left lateral posture (SLL) to optimize imaging quality. ⋯ SLL is not a suitable modality for the assessment of functional status or for the derivation of target heart rates for exercise training in UP posture. However, SLL leg cycle ergometry exercise provokes a comparable stimulus for the detection of coronary artery disease, as it will increase myocardial oxygen demand to the same extent as UP leg cycle exercise.
