Cardiopulmonary Flashcards
Upon cardiac auscultation the S3 sound corresponds with what physiological process in the heart?
A. mitral and tricuspid valve closure
B. rapid filling of dilated ventricles during diastole
C. aortic and pulmonic valve closure
D. filling of hypertrophic ventricles during diastole
B. rapid filling of dilated ventricles during diastole *the S3 sound is associated with increased filling pressures (e.g. mitral regurge and heart failure) and is more common in dilated ventricles. Usually abnormal, but normal in children and pregnant women.
Please label points A through D on the following pressure volume loop.
A. Mitral valve opens
B. Mitral valve closes
C. Aortic vavle opens
D. Aortic valve closes
