EXERCISE STRESS TESTING IN THE 21st CENTURY.

Until recent decades, exercise testing with electrocardiographic monitoring (ET) was a fundamental test to evaluate individuals with suspected or known cardiovascular disease (CVD). Since its inception, the landscape of CVD has profoundly changed; classical indications such as the diagnosis of ischemic heart disease have been progressively superseded by other modalities. ET can still, however, provide valuable data across the cardiovascular continuum. In this focused two-part article, we appraise the role of ET in contemporary settings: part I provides an overview of core parameters, while part II addresses select main areas of interest.
