10. A method, comprising:
obtaining an electroanatomical map, which maps a portion of a heart of a subject while the heart experiences an arrhythmia;
obtaining a sequence of images of the heart acquired by an ultrasonic probe, the sequence including one or more arrhythmic images acquired while the heart experiences the arrhythmia and one or more rhythmic images acquired while the heart is in sinus rhythm,
the ultrasonic probe including a sensor that outputs, during the acquisition of the sequence of images, a signal indicating a location and an orientation of the probe in a coordinate system of the electroanatomical map;
based on the signal, identifying, in one of the arrhythmic images, an anatomical portion represented by a particular portion of the electroanatomical map the anatomical portion being a focal point of the arrhythmia;
by tracking the anatomical portion forward or backward through the acquired sequence of images, identifying the anatomical portion in at least one of the rhythmic images; and
displaying an output in response to identifying the anatomical portion in the at least one of the rhythmic images.
