A Methodology for Measuring the Chronotropic and Inotropic Effects During Autonomic Tests

摘要

A methodology for autonomic testing, that reflects both chronotropic and inotropic effects and their relationship is presented. ECG and impedance cardiogram (ICG) are recorded from the subject during each test. The method provides plots of heart rate, pre-ejeclion period and blood ejection velocity. This non-invasive technique has been applied to normal subjects and patients with autonomic disorders. Some analysis techniques arc proposed, as future research directions, to improve the clinical application of the method.
