Abstract

A method for obtaining unipolar epicardial potentials from the in vivo canine heart while the dog is in the MR scanner was developed. Using tagged MRI, spatially and temporally registered electrical and mechanical activation maps were obtained in the ventricularly paced canine heart. The temporal precision in spatially matching electrical and mechanical activation times was estimated to be 2-4 ms.
