D. Identify problems with the tachogram data
E. Correct tachogram data
“Results reveal that even a single heart period artifact, occurring within a 2-min recording epoch, can lead to errors of estimate heart period variability that are considerably larger than typical effect sizes in psychophysiological studies.”
—Berntson & Stowell, 1998

Cardiovascular insights are much easier to achieve with this new integration from BIOPAC and CNSystems. The CNAP™ technology is now fully incorporated in a single BIOPAC amplifier for the MP160 system where it can be fully controlled by AcqKnowledge Software—optimized for research utilizing core CNAP clinical technology.
What you will learn:
• Correct equipment set up and operation
• Principles of the CNAP measurement technology
• How to get reproducible data
• How to interface equipment and optimize multiple measurements
• Automatic blood pressure analysis
• Application of the “Focus Areas” feature in AcqKnowledge Software
