There are several types of Doppler echocardiography, including:
1. Color Doppler: This form adds color to the standard ultrasound images to show the direction and speed of blood flow. 2. Spectral Doppler: This type provides a graphical representation of blood flow velocities over time. 3. Continuous Wave Doppler: Used for measuring high velocities of blood flow, particularly useful in detecting severe valve diseases. 4. Pulsed Wave Doppler: Measures blood flow velocities at specific locations within the heart, ideal for assessing localized issues.
