Apparatus and method for sensing spatial displacement in a heart |
摘要 |
An electrical lead includes an elongate body having a proximal end, and a sensing unit capable of resolving a change in a spatial configuration of the electrical lead. A medical device includes a control unit, an elongate body having a proximal end coupled with the control unit, and a sensing unit capable of resolving a change in a spatial configuration of the electrical lead and relating it to the amount of blood ejected from the heart. A method includes receiving a signal transmitted from a lead disposed within a heart and determining a change in a dimension of the heart, due to the heart beating, based upon the signal.
