Physiological and pathological aspects of exercise left ventricular function

Abstract

Measures of left ventricular function during exercise provide information that is more accurate than the exercise ECG in the diagnosis of coronary artery disease, supportive of the data provided by myocardial perfusion studies, and of great prognostic significance. We review basic methods for evaluating left ventricular function during exercise and responses to various types of exercise, including incremental exercise and exercise training conditions. Additionally, we review changes in both incremental exercise test responses and responses to training in various pathological conditions. Case reports are included to illustrate the utility of measuring left ventricular function during exercise.
