dynamic forces acceleration signals may be used in part to determine tilt direction orientation or other directional attributes of electrode 28 and may assist in providing a clear picture of electrode 28 interaction with an associated treatment area signals may also be used in conjunction with one or more visualization systems to provide a more complete view of a treatment area such as a cardiac chamber as well as the position of an electrode such as electrode 28 relative to the treatment area acceleration signals may be used to determine local health of cardiac tissue such as by determining the force with which cardiac muscle displaces an electrode 28 in contact therewith additionally signals used to determine contact with tissue may for example increase the safety of ablation procedures by ensuring ablation energy is provided to an electrode only when the electrode is in contact with tissue in addition to the foregoing embodiment of the present invention may include catheters including additional features for example the present teachings may be included in an irrigated catheter although embodiments of this invention have been described above with a certain degree of particularity those skilled in the art could make numerous alterations to the disclosed embodiments without departing from the spirit or scope of this invention all directional references e g upper lower upward.
