GLOSSARY OF TERMS USED IN TIME SERIES ANALYSIS OF CARDIOVASCULAR DATA

|LEVEL 0| |HOMEPAGE|

A pulse appearing in the blood pressure wave during the diastolic phase.

The term derives from Greek: Di (=twice) +Krotos (=beat). It should not be confused with the dicrotic notch, or incisura dicrota, i.e., the notch separating the systolic from the diastolic part of the pressure wave.
 

Dicrotic pulse (which is a pulse with exaggerated dicrotic wave) literally means twice beating pulse, like bisferiens pulse. However, the dicrotic pulse has the second pulse during diastole, while the bisferiens pulse has the second pulse during systole.
