“…Previo-uly we reported that CASI produces equivalent results to those of sonomicrometry in the arrested heart [3]. In addition, CAWS capability of determining myocardial function with high spatial resolution in the isolated rabbit heart was also shown [4]. Herein, we utilize CASI to map regional mechanical function ip the intact porcine heart during ventricular pacing.…”

Herein we ntllize an advanced phase correlation technique to track ventricular surface markers on the intact porcine heart in order to assess the functionality of the regional tissue. Pacing at 150 heats per minute reduces the regional stroke work siguilicantly and produces an increasing functional pattern distal to the stimulator.
