This lecture covers the experience of ergometry, focusing on the use of an ergometric bike for measuring heart rate, respiration, and other physiological parameters. The lecture explains the setup of the bike, the integration of a blood pressure measuring device, and the continuous monitoring of heart rate. It also discusses the analysis of heart rate signals, the importance of proper electrode placement, and the challenges of artifact detection. The lecture emphasizes the reliability of the measurement methods and the need for accurate data processing.
