ABSTRACT:
A method and appartus are provided for measuring left atrial pressure by inserting a sensing probe into the esophagus and positioning the probe so that pressure from the left atrium is sensed by the probe. More particularly, the invention provides a method for measuring left atrial pressure by inserting a balloon-containing catheter into the esophagus and positioning the catheter so that when the balloon is inflated, pressure from the left atrium affects the balloon; inflating the balloon; and, determining the left atrial pressure by the effect of the atrial pressure upon the balloon.
