Cardio5 Flashcards
Cardiac cycle Cardiac sounds Jugular venous pulse
Phases - Left ventricle:
-Isovolumetric contraction
Period between mitral valve closure and aortic valve opening
Phases - Left ventricle:
-Systolic ejection
Period between aortic valve opening and closing
Phases - Left ventricle:
-Isovolumetric relaxation
Period between aortic valve closing and mitral valve opening
Phases - Left ventricle:
-Rapid filling
Period just after mitral valve opening
Phases - Left ventricle:
-Reduced filling
Period just before mitral valve closure
What are the Phases of the left ventricle in the cardiac cycle?
Isovolumetric Contraction Systolic ejection Isovolumetric Relaxation Rapid filling Reduced filling
Which phase (left ventricle) of the cardiac cycle is the period of highest O2 consumption?
Isovolumetric Contraction
S1
Mitral & Tricuspid valve Closure
S2
Aortic & Pulmonary valve Closure
S3
In early Diastole during Rapid Ventricular Filling phase
S4
“Atrial Kick”
Late Diastole
Where is S1 loudest?
Mitral area
Where is S2 loudest?
Left Sternal Border
What is S3 associated with?
INcreased Filling Pressures
-i.e., mitral regurg, CHF
Dilated Ventricles
*Normal in children and Pregnant woment
What is S4 associated with?
High Atrial Pressure
Ventricular Hypertrophy
-Left atrium must push against still LV wall
