A medical system includes an ultrasound probe, a treatment probe, and processor. Ultrasound probe and treatment probe are configured for insertion into an organ, to, respectively, image a volume of the organ, and introduce a treatment device therein. The probes respectively include first sensor configured to output first signals indicative of first positions of an ultrasound transducer array of the probe inside the organ, and second sensor configured to output second signals indicative of second positions of the treatment device inside the organ. The processor is configured to receive tags added to ultrasound images acquired using the ultrasound probe and mark tissue regions of the organ, register first positions of ultrasound transducer array and second positions of treatment device with one another, using registration, track relative position between treatment device and tagged tissue regions, and (iv) alert user when treatment device is within predefined proximity to tagged tissue region.

A method includes storing an anatomical map of at least a portion of a surface of a heart. Respective electrogram (EGM) signal amplitudes measured at respective positions on the surface of the heart are stored. Based on the on the EGM signal amplitudes, defined are: one or more first regions of the surface in which the EGM signal amplitudes are fractionated, and one or more second regions of the surface in which the EGM signal amplitudes are non-fractionated. A first surface representation is generated for the fractionated EGM signal amplitudes in the first regions. Propagation times are extracted from the non-fractionated EGM signal amplitudes in the second regions, and a second surface representation of the propagation times is derived. The first and second surface representations of the respective first and second regions of the surface are simultaneously presented, overlaid on the anatomical map.
