1. An esophageal probe for use in diagnosis or as a stimulant comprising:

  • a flexible elongated conduit having a proximal end and a distal end;

    a first EKG electrode positioned on said conduit near said distal end;

    a first ultrasonic transducer longitudinally positioned on said conduit in selective spaced relationship to said first electrode;

    a second ultrasonic transducer longitudinally positioned on said conduit in selective spaced relationship to said first transducer;

    a second EKG electrode positioned on said conduit in selective spaced relationship to said second ultrasonic transducer and spaced at a distance from the proximal end;

    the ultrasonic transducers being positioned between the EKG electrodes, conductive pathways connected to said electrodes and transducers;

    said proximal end being adapted for receiving the conductive pathways from each of the electrodes and transducers for connection with electrocardiological and echocardiographic devices; and

    wherein the selective spaced relationship between each electrode and transducer is equal and not more than 5 centimeters.
