摘要：
A method for anatomical diagnosis includes measuring,using a catheter that includes a position sensor and anelectrode, over multiple cycles of a beating heart,electrical activity and mechanical motion at a plurality oflocations contacted by the catheter on a heart wall within achamber of the heart. Based onthe measured mechanicalmotion, a magnitude of a mechanical strain is computed overthe cycles at the locations. In oneembodiment, thecomputed strain is used in identifying a group of thelocations at which the magnitude of the mechanical strain isbelow a predefined strain threshold and a voltage of theelectrical activity is below a predefined voltage thresholdas a locus of scar tissue. In anotherembodiment, apathological condition of the heart is identified based on acharacteristic of the mechanical strain computed over theleft ventricle during the diastolic phase
