A method and apparatus for detecting cardiac events. Ultrasonic data comprising a heart cycle is acquired by a probe. Tissue velocities associated with the ultrasonic data are detected. One of a maximum and a minimum value is detected based on the tissue velocities. A time within the heart cycle associated with the maximum or minimum value is determined, and a cardiac event is detected with respect to the time within the heart cycle and the maximum or minimum value.
