WebUnlike systolic sounds, diastolic sounds are low-pitched; they are softer in intensity and longer in duration. Except for S2, these sounds are usually abnormal in adults, although an S3 may be physiologic up to age 40 and during pregnancy. S2 occurs at the beginning of diastole, due to aortic and pulmonic valve closure. WebJan 7, 1997 · Ventricular diastolic dysfunction implies the requirement for elevated filling pressures to maintain cardiac output, resulting ultimately in congestive cardiac failure. Normal ventricular performance during early diastole is largely dependent on the process of active myocyte relaxation. WebResults: Peak negative dP/dt was decreased and isovolumetric left ventricular relaxation time constant increased by coronary stenoses; however neither changed significantly during simulated exercise.
