Abstract: An ultrasound imaging system includes a video processor receiving coherent echo signals from a beamformer. The video processor converts the coherent echo signals to image data, which are applied to a streaming digital video processor. The system also includes an ECG monitor and processor that obtains an ECG signal and uses the signal to provide heart cycle data indicative of the beginning and end of each of the plurality of heart cycles. The streaming digital video processor converts the image data into streaming digital data, which are divided into the heart cycle sections as indicated by the heart cycle data. The system also includes a digital video disk recorder that records a digital video disk containing the digital video data divided into chapters containing respective heart cycle sections. The recorder may also record chapters of ECG data derived from the ECG signal along with the digital video data.
