Before reading this article, check out these basic guidelines for ensuring good data collection which are universally applicable. Now we will get a bit more focused, and talk about signal specific data quality issues that can arise and how to deal with them. Disclaimer: Labeling data “good” or “bad” is […]
All About Cardiac Impedance Part 6: Deriving Respiration
Select analysis version to view the applicable content: For our final entry in the series on cardiac impedance, we are going to step back from analyzing the impedance signal directly and examine another way in which it can be used – to provide an index of respiration. Why this […]
All About Cardiac Impedance Part 1: Introduction to Cardiac Impedance
All About Cardiac Impedance Cardiac impedance is a measurement of the mechanical activation of the heart. By recording cardiac impedance in conjunction with the electrical activation of the heart, the electrocardiogram (ECG), we can gain insight into sympathetic nervous system influence through measures such as Pre-Ejection Period, Stroke Volume, and Cardiac […]
