A method includes acquiring a bipolar signal from a first electrode and a second electrode contacting a first location and a second location, respectively, in a heart of a living subject. The method further includes acquiring a unipolar signal from the first electrode while in contact with the first location, and deriving from the bipolar signal and the unipolar signal a point in time at which the first location is generating the unipolar signal. The method also includes computing a metric for a conduction velocity of the unipolar signal at the first location based on a shape of the unipolar signal at the point in time.

Tissue conduction velocity

Cardiac electrograms are recorded in a plurality of channels. Beats are classified automatically into respective classifications according to a resemblance of the morphologic characteristics of the beats to members of a set of templates. Respective electroanatomic maps of the heart are generated from the classified beats.

Automatic creation of multiple electroanatomic maps

A method, consisting of inserting a probe having a force sensor into a body cavity of a patient, and receiving from the force sensor a plurality of measurements, each of the measurements indicative of a force applied to the force sensor. The method further includes detecting that the measurements received over a period of time of at least a specified duration have not varied by more than a predefined amount, and setting a baseline of the force sensor, for use in further measurements, to a value based on the measurements received during the period.
