Monophasic, Biphasic & Triphasic Spectral Doppler Waveforms | Vascular Ultrasound Analysis (USG) *Cases Intro - 0:00 Monophasic - 0:10 Biphasic - 2:17 Triphasic - 4:28 Monophasic Waveform: Represents a single forward flow component throughout the cardiac cycle. The waveform has a rounded, blunted appearance and lacks the characteristic sharp peak. The waveform does not cross the baseline Biphasic Waveform: Consists of a forward flow during systole and a reversed flow component during early diast

Cardiac tamponade Cardiac tamponade is a clinical diagnosis with key physical (elevated venous pressure, pulsus paradoxus, hypotension) and echocardiographic (chamber collapses, abnormal venous flows, exaggerated respiratory variation in venous and cardiac flows, and vena caval plethora) findings. Echocardiographic findings suggestive of pericardial tamponade include: inferior vena cava (IVC) plethora, diastolic blunting of hepatic vein forward flow, respiratory inflow variation across the trisc
