Abstract
A sensing system for detecting the frequency and amplitude of motion of a patient's diaphragm, having a transducer for detecting movement, transvenously implantable in a patient's cardiovascular system; a lead coupled to the transducer, transvenously implanatable in a patient's cardiovascular system; and a sensing instrument coupled to the lead for correlating transducer movement with the frequency and amplitude of diaphragm motion. A method for sensing the frequency and amplitude of motion of a patient's diaphragm including transvenously implanting in a patient's cardiovascular system a transducer capable of measuring movement frequency and amplitude; detecting the frequency and amplitude of movement of the transducer; and correlating transducer movement with the frequency and amplitude of the patient's diaphragm movement.
