267 – Wireless Noninvasive Cardiovascular Reactivity Measurement

A significant methodological concern in impedance cardiography is related to the impact of movement artifacts on recorded data. Ensemble averaging methods provide a strategy to remove these artifacts. Wearable and ubiquitous technology for physiological recording will likely be required to make use of these types of signal averaging techniques.

The BioNomadix wireless physiology system can be used to perform real-time, beat-by-beat and ensemble averaged measurements related to cardiovascular reactivity, including Heart Rate (bpm), Left Ventricular Ejection Time (B-X ms), Pre-ejection Period (Q-B ms), Electromechanical Systole (Q-X ms), Stroke Volume (ml) and Cardiac Output (l/min).

This application note explains the required setup and provides data samples.
