Abstract:
Interpretation of the pressure waveforms obtained during cardiac catheterization is a skill that is useful to the clinical cardiologist and should be dominated by the interventional cardiologist. We present a systematic review of the information that can be obtained from carefully recorded pressure tracings of the heart and large vessels. Analysis of pressure recordings is approached as to their absolute values, their waveforms, the relationship between simultaneous recordings in different chambers or vessels, and the provocative maneuvers that can be required to improve diagnostic precision.

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
