Tissue Doppler echocardiography is a new ultrasonographic approach to the quantification of myocardial function. It is based on the interrogation of the high amplitude, low velocity reflected ultrasound signals from the myocardium. Velocity data can be obtained during pulsed‐ or color Doppler methodologies. Color Doppler data can be processed to determine regional acceleration, strain, strain rate, delay, and amplitude of motion. Color myocardial Doppler frame rates of up to 200 s −1 can be implemented by parallel processing of the data, thus overcoming the early temporal resolution limitations of the technique.
