A recent report in Harefuah introduced cardiopulmonary exercise testing (CPX) and its role in evaluating effort intolerance. Despite the fact that multiple guideline documents and scientific statements have been published in the last few years by the leading European and American societies, summarizing the incremental information supplemented by the addition of ventilatory gas exchange measurements, CPX continues to be underutilized by the practicing clinician. The reasons for this are many and include the requirement for additional equipment, the lack of understanding of the physiological basis by the practicing clinicians, and the seemingly complicated graphical report of this technique. We shall review the physiological basis of the technique, and summarize the key CPX variables and their clinical implications.
