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.
