Common Errors and Artifacts in Hemodynamic Measurements

Hemodynamic pressure recordings can provide valuable information regarding cardiac physiology and pathology. It is important to avoid artifacts and errors in the recording of high-quality pressure tracings. In this exercise, we will review common errors and methods to identify and avoid misleading information.

You will learn:

  • To identify common errors in pressure recordings including over-damping, under-damping (“ring” artifact), catheter whip or “fling”, hybrid waveforms, catheter malposition, loose connections, catheter kinks, and/or faulty transducers.
  • To define the physical principles associated with errors in pressure recordings.
  • To learn methods to correct errors and to record diagnostic tracings.
