Fetal mitral valve waveform
WebDec 29, 2024 · The cardiac cycle is defined as a sequence of alternating contraction and relaxation of the atria and ventricles in order to pump blood throughout the body. It starts at the beginning of one heartbeat and ends at the beginning of another. The process begins as early as the 4th gestational week when the heart first begins contracting. WebHow to perform S’ Wave Measurement. Place cursor over lateral annulus of tricuspid valve; Pulse Wave Doppler and TDI; Decrease gains to avoid measuring ‘noise artifact’ Identify maximum systolic velocity ABOVE the baseline—‘S’ Wave’ Challenges/Limitations to measurement: Angle Dependent; Not fully representative of global RV function
